Routine Descriptions

THM_CHECK_VALID_NAME

[Next Routine] [List of Routines]
NAME:
thm_check_valid_name
PURPOSE:
checks a string or array input against another array and 'all' to
find matches.
CALLING SEQUENCE:
 ok_names = thm_check_valid_name(names, valid_names)
INPUT:
 names = a string array of possible names for data types, stations,
 etc...
 valid_names = those names that will be valid
OUTPUT:
 ok_names = the valid data names, if there are none, then the null
 string is returned
KEYWORDS:
 include_all = if set, include 'all' in the possible datanames
 ignore_case = if set converts all inputs 
 loose_interpretation = if set, adds wild card '*'s to each end of
                        the input names -- used in thm_load_mom, and
                        thm_load_esa, where there are many L2
                        variables.
 no_warning = if set, do not issue a warning if the input is invalid

THM_CONFIG

[Previous Routine] [Next Routine] [List of Routines]
  PRO themis_config

  This procedure serves as the themis configuration file.  It sets global (system)
  variables and initializes devices

  This procedure will define the location of data files and the data server.
  This procedure is intended to be called from within the "THM_INIT" procedure.

  This should be the only THEMIS file that requires modification for use in different
  locations.

  There is no need to modify this file if:
     - Your computer is an SSL UNIX machine that mounts "/disks/data/"   (i.e. ALL Linux and Solaris machines at SSL)
     - You use a portable computer that will be caching files on a local hard drive.


  Settings  in this file will be overridden by settings in the environment.
  (see setup_themis or setup_themis_bash for examples of setting environment
  variables on UNIX-like systems.  The environment can also be set on Windows
  systems.)

  KEYWORDS

THM_DATA2LOAD

[Previous Routine] [Next Routine] [List of Routines]
NAME:
 thm_data2load
PURPOSE:
 returns a list of variables that can be loaded for a given THEMIS
 instrument. For the most part, it calls the appropriate thm_load
 routine with the /valid_names keyword set. The dataypes and
 valid_names keywords are used inconsistently in the thm_loads, and
 do not allow for the distinction between level2 data that is
 to be input from level2 files, and level2 data the is to be input
 from level1 files and calbrated, cotrans'ed, etc... but has the same
 name as an L2 variable. Designed to be called from
 thm_ui_valid_dtype.pro
CALLING SEQUENCE:
 dtyp = thm_data2load(instrument, level)
INPUT:
 instrument = the THEMIS instrument: one of:
           ['asi', 'ask', 'esa', 'efi', 'fbk', 'fft', 'fgm', $
            'fit', 'gmag', 'mom', 'scm', 'sst', 'state', 'bau', 'hsk', 'trg']
 level = 'l1' for any data that can be gotten from the l1 file --
         including calibrated, etc... 'l2' for data gotten from L2
         files. 'l10' for data that only is loaded from L1 files. For
         ESA data, 'L10' data and 'L1' data are gotten from the
         packet files.
OUTPUT:
 dtyp = a string array that can be used as an input to the datatype
        keyword for the given instrument
HISTORY:
 started on 31-Jan-2008, jmm, jimm@ssl.berkeley.edu, this is under
 development for the next 6 months or so.
 9-apr-2008, jmm, added all instruments, for Version 4_00

			(infinite loop is feared when catch statement has been call 1000 times)
	   DONT_DELETE_DATA:  keyword to not delete all existing tplot variables before loading data in for
			        the overview plot (sometimes old variables can interfere with overview plot)

 Example: thm_gen_overplot,probe='a',date='2007-03-23',dur=1
	   The above example will produce a full day plot in the X window.

THM_INIT

[Previous Routine] [Next Routine] [List of Routines]
PROCEDURE:  thm_init
PURPOSE:    Initializes system variables for themis.  Can be called from idl_startup to set
            custom locations.

 The system variable !THEMIS is defined here.  The elements of this structure are explained below:

 !THEMIS.LOCAL_DATA_DIR    This is the root location for all THEMIS data files.
                  The THEMIS software expects all data files to reside in specific subdirectories relative
                  to this root directory.;

 !THEMIS.REMOTE_DATA_DIR   This is the URL of the server that can provide the data files.
                  (default is: "http://sprg.ssl.berkeley.edu/data/themis/")
                  if the software does not find a needed file in LOCAL_DATA_DIR,
                  then it will attempt to download the data from the URL and REMOTE_DATA_DIR is defined,
                  the software will attempt to download the file from REMOTE_DATA_DIR, place it in LOCAL_DATA_DIR
                  with the same relative pathname, and then continue processing.


KEYWORDS:
   RESET:           Reset !themis to values in environment (or values in keywords).
   LOCAL_DATA_DIR:  use given value for local_data_dir, rather than environment. Only works on
                    initial call or reset.
   REMOTE_DATA_DIR: Use given value for remote_data_dir, rather than env.  Only works on inital
                    call or reset.
   NO_COLOR_SETUP   do not set colors if already taken care of

 Typical examples:

          Desktop UNIX/LINUX computer located at SSL
   LOCAL_DATA_DIR  = '/disks/data/themis/'               ; This master directory is read only.
   REMOTE_DATA_DIR = ''                                  ; Should be empty sting. (/disks/data/themis and server are the same)

          Desktop WINDOWS computer located at SSL
   LOCAL_DATA_DIR  = '\\justice\data\themis\'            ; Justice is a samba server (physically the same as /disk/data/themis)
   REMOTE_DATA_DIR = ''

          laptop WINDOWS computer located far from a data server, but with internet connection.
   LOCAL_DATA_DIR  = 'C;\data\themis\'                              ; Local (portable) directory on laptop
   REMOTE_DATA_DIR = 'http://sprg.ssl.berkeley.edu/data/themis/'    ;  URL used to download data to LOCAL_DATA_DIR

          MacOS computer located away from SSL without a nearby data server
   LOCAL_DATA_DIR  = '/data/themis/'                              ; Local (portable) directory on laptop
   REMOTE_DATA_DIR = 'http://sprg.ssl.berkeley.edu/data/themis/'    ;  URL used to download data to LOCAL_DATA_DIR

   Note: If automatic downloads are used. (i.e. REMOTE_DATA_DIR is not an empty string) the user must ensure that
   LOCAL_DATA_DIR is writeable.

   Note to WINDOWS users: the WINDOWS version of IDL accepts both the '\' and '/' character as the directory
   separation character. The converse is not true.

THM_LOAD_PROC_ARG

[Previous Routine] [Next Routine] [List of Routines]
Procedure: THM_LOAD_PROC_ARG

Purpose:  Generic argument validation routine for THEMIS Data File Loading
   routines, meant to be called by
   instrument-specific thm_load procedures.

keywords:
  post_process_proc: name of procedure to call after cdf2tplot is called
                     will be called w/ keywords sname, dt (datatype), lvl,
                     and _extra.
  relpath_funct: name of routine to call in place of file_dailynames
                 may simply be a wrapper.
                 will be called w/ keywords sname, dt (datatype), lvl,
                 and _extra.
  cdf_to_tplot: user-supplied procedure to override cdf2tplot
  sname  = site or probe name. The default is 'all',
  type_sname = string, set to 'probe' or 'site'
  vsnames = space-separated list of valid probes/sites
  datatype = Can be any datatype from the list of valid datatypes
             or 'all'
  vdatatypes = space-separated list of valid data types
  file_vdatatypes = space-separated list of file types corresponding to each
          valid data type.  If there is a one-to-one correpspondence
          between filetype and datatype, vfiletypes may be left undefined.
          If all datatypes are in a single file, then vfiltypes may contain
          a single name, rather than a list.
  vL2datatypes= space-separated list of datatypes valid for L2 data
  vL2coord= space-separated list of coordinates valid for L2 data
  file_vL2datatypes=same as file_vdatatypes, but for L2 data.  Defaults to
          value of file_vdatatypes.
  TRANGE= (Optional) Time range of interest  (2 element array), if
          this is not set, the default is to prompt the user. Note
          that if the input time range is not a full day, a full
          day's data is loaded
  level = the level of the data, the default is 'l1', or level-1
          data. A string (e.g., 'l2') or an integer can be used. 'all'
          can be passed in also, to get all levels.
  vlevels=A space-separated list of valid levels, e.g. 'l1 l2'
  proc_type =  the type of data, i.e. 'raw' or 'calibrated'. This is
          for validating the 'type' keyword to thm_load procs.
  vtypes =A space-separated list of valid types, e.g. 'raw calibrated'
          No validation on proc_type if not set.
  deftype = default for type.  only applied to L1.  If not supplied, 
            then 'calibrated' will be uses as the default value.
  CDF_DATA: named variable in which to return cdf data structure: only works
          for a single spacecraft and datafile name.
  VARNAMES: names of variables to load from cdf: default is all.
  /GET_SUPPORT_DATA: load support_data variables as well as data variables

THM_LOAD_XXX

[Previous Routine] [Next Routine] [List of Routines]
Procedure: THM_LOAD_XXX

Purpose:  Generic THEMIS Data File Loading routine, meant to be called by
   type specific thm_load procedures.

keywords:
  post_process_proc: name of procedure to call after cdf2tplot is called
                     will be called w/ keywords sname, dt (datatype), lvl,
                     and _extra.
  relpath_funct: name of routine to call in place of file_dailynames
                 may simply be a wrapper.
                 will be called w/ keywords sname, dt (datatype), lvl,
                 and _extra.
  cdf_to_tplot: user-supplied procedure to override cdf2tplot
  sname  = site or probe name. The default is 'all',
  type_sname = string, set to 'probe' or 'site'
  /all_sites_in_one: set this if all sites are contained in a single file.
  vsnames = space-separated list of valid probes/sites
  datatype = Can be any datatype from the list of valid datatypes
             or 'all'
  vdatatypes = space-separated list of valid data types
  file_vdatatypes = space-separated list of file types corresponding to each
          valid data type.  If there is a one-to-one correpspondence
          between filetype and datatype, vfiletypes may be left undefined.
          If all datatypes are in a single file, then file_vdatatypes may
          contain a single name, rather than a list.
  TRANGE= (Optional) Time range of interest  (2 element array), if
          this is not set, the default is to prompt the user. Note
          that if the input time range is not a full day, a full
          day's data is loaded
  level = the level of the data, the default is 'l1', or Level 1
          data. A string (e.g., 'l2') or an integer can be used.
  vlevels=A space-separated list of valid levels, e.g. 'l1 l2'
  proc_type =  the type of data, i.e. 'raw' or 'calibrated'. This is
          for validating the 'type' keyword to thm_load procs.
  vtypes =A space-separated list of valid types, e.g. 'raw calibrated'
  vL2datatypes= space-separated list of datatypes valid for L2 data
  vL2coord= space-separated list of coordinates valid for L2 data
  file_vL2datatypes=same as file_vdatatypes, but for L2 data.  Defaults to
          value of file_vdatatypes.
  coord = coordinate system of data to  be loaded.  For L2, may be an array or
          space-separated list, which will checked against vL2coord.
          For L1, no checking: passed on to post_process_proc.
  CDF_DATA: named variable in which to return cdf data structure: only works
          for a single spacecraft and datafile name.
  VARNAMES: names of variables to load from cdf: default is all.
  /GET_SUPPORT_DATA: load support_data variables as well as data variables
                      into tplot variables.
  /DOWNLOADONLY: download file but don't read it.
  /NO_UPDATE: prevent contact to server if local file already exists.
  /valid_names, if set, then this routine will return the valid probe, datatype
          and/or level options in named variables supplied as
          arguments to the corresponding keywords.
  files   named varible for output of pathnames of local files.
  /VERBOSE  set to output some useful info
  suffix  suffix to add to names of tplot variables loaded from CDF
  SCM_CAL: structure that contains calibration paramters

Notes:
  This routine is (should be) platform independent.
