## RBSP_EMFISIS_CONFIG

[Next Routine] [List of Routines]

      PRO rbsp_emfisis_config

      This procedure serves as the RBSP EMFISIS 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 "RBSP_EMFISIS_INIT" procedure.

      This should be the only RBSP EMFISIS 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
         no_color_setup: do not set colors if already taken care of

## RBSP_EMFISIS_INIT

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

    PROCEDURE:  rbsp_emfisis_init
    PURPOSE:    Initializes system variables for RBSP EMFISIS.  Can be called from idl_startup to set
                custom locations.

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

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

     !RBSP_EMFISIS.REMOTE_DATA_DIR   This is the URL of the server that can provide the data files.
                      (default is: "https://themis.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.
                      (NOT YET IMPLEMENTED)

    KEYWORDS:
       RESET:           Reset !rbsp 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/rbsp/'               ; This master directory is read only.
       REMOTE_DATA_DIR = ''                                  ; Should be empty string. (/disks/data/rbsp and server are the same)

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

              laptop WINDOWS computer located far from a data server, but with internet connection.
       LOCAL_DATA_DIR  = 'C;\data\rbsp\'                              ; Local (portable) directory on laptop
       REMOTE_DATA_DIR = 'https://themis.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/rbsp/'                              ; Local (portable) directory on laptop
       REMOTE_DATA_DIR = 'https://themis.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.

## RBSP_SUBTRACT_DCFIELD

[Previous Routine] [List of Routines]

    *****************************************************************************************

      FUNCTION :   rbsp_remove_dcfield  (OBSOLETE: SEE rbsp_efw_DCfield_removal_crib.pro)
      PURPOSE  :   Subtract off DC magnetic field from Bw values. Saves as new tplot files

      CALLED BY:   see rbsp_efw_DCfield_removal_crib

      REQUIRES:   Need: SSL THEMIS software and IDL Geopack DLM both found at
    			   http://themis.ssl.berkeley.edu/software.shtml

      INPUT:
    		magname -> tplot name of the [n,3] magnetic field data in GSM
    		posname -> tplot name of the [n,3] GSM position data
    		probe   -> 'a' or 'b'
    		model   -> Any of the Tsyganenko models or IGRF. Defaults to 't96'

      EXAMPLES:    see remove_dcfield_crib.pro

    				Produces the following variables (ex for magname = 'rbspa_mag_gsm', model='t96')
    					rbspa_mag_gsm_t96
    					rbspa_mag_gsm_t96_dif

    					If the model is not t89 then produces:
    					rbspa_mag_gsm_t96_wind
    					rbspa_mag_gsm_t96_wind_dif
    					rbspa_mag_gsm_t96_ace
    					rbspa_mag_gsm_t96_ace_dif
    					rbspa_mag_gsm_t96_omni
    					rbspa_mag_gsm_t96_omni_dif

       NOTES:    ruthlessly pilfered from THEMIS crib sheets
                 Subtracts off Tsyganenko values using input from ACE, Wind and OMNI, as
    			  well as user defined input.
