function: thm_interpolate_state
Purpose: interpolates the low res STATE file
all variables are structures as produced by get_data
keywords:
Examples:
tha_spinper_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinper=thx_spinper) --> linear interpolation
tha_spinphase_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinper=thx_spinper,thx_spinphase=thx_spinphase) --> phase constructed according to the nearest neighbor spin phase, spin period
tha_spinras_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinras=thx_spinras) --> linear interpolation
tha_spindec_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spindec=thx_spindec) --> linear interpolation
tha_spinalpha_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinalpha=thx_spinalpha) --> linear interpolation
tha_spinbeta_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_spinbeta=thx_spinbeta) --> linear interpolation
tha_pos_highres=thm_interpolate_state(thx_xxx_in=thx_xxx_in,thx_pos=thx_pos) --> spline interpolation

Procedure: THM_LOAD_STATE
Purpose: Loads THEMIS STATE (orbit and attitude) data
;keywords:
probe = Probe name. The default is 'all', i.e., load all available probes.
This can be an array of strings, e.g., ['a', 'b'] or a
single string delimited by spaces, e.g., 'a b'
datatype = The type of data to be loaded, can be an array of strings
or single string separate by spaces. The default is 'pos vel'
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
version = the version of the state file, one of 'v00', 'v01', 'v02', 'v03'.
defaults to 'v01'
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.
suffix= suffix to add to tplot variable names. Note: this will get added
support_data variables as well as regular data variables.
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_download: use only files which are online locally.
/NO_UPDATE: prevent contact to server if local file already exists.
relpathnames_all: named variable in which to return all files that are
required for specified timespan, probe, datatype, and level.
If present, no files will be downloaded, and no data will be loaded.
/valid_names, if set, then this routine will return the valid probe, datatype
level, and version 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
coord: Can specify the coordinate system you would like data
returned in.
no_spin: if set, do not call thm_load_spin to load spinmodel data.
Example:
thm_load_state
Notes:
Modifications:
If /GET_SUPPORT_DATA and ~/NO_SPIN, then call THM_LOAD_SPIN, W.M.Feuerstein,
4/10/2008.
Delete th?_spin* TPLOT variables after calling THM_LOAD_SPIN (as long as
~/KEEP_SPIN_DATA), add KEEP_SPIN_DATA kw, include a couple of (normally
commented) lines to chck consistency of spinmodel, WMF, 4/10/08.
coordinate systems of returned variables:
*_pos : gei
*_vel : gei
*_ras : gei
*_dec : gei
*_alpha : spg
*_beta : spg
*_spinper : none(listed in dlimits as unknown)
*_spinphase : none(listed in dlimits as unknown)
*_roi : none(listed in dlimits as unknown)
*_man : none(listed in dlimits as unknown)
If you modify the d_names constant make sure to make the
corresponding changes to the c_names constant

NAME:
thm_spin_phase
Purpose:
Use sunpulse data produced by thm_sunpulse to get spinphase at abitrary times
Input Parameters:
time_dat: double precision array: times of data points at which
interpolates are desired.
Output Parameters:
spinpha_int: interpolated spin phase
Keywords:
Probe: a single probe name. e.g. 'a'
suffix: suffix on tplot variable (thx_state_sunpulse[_suffix])
Optional Input Parameters (If not present, then state data will be
loaded from standard state tplot variables, using probe keyword)
sunpulse: double precision array: times of sunpulses
sunp_spinper: spin period at each sunpulse time

NAME:
thm_sunpulse
Purpose:
Interpolate spin phase to have same time resolution as time_dat
Keyword:
probe: string indicating probe. Array of strings, or a string
like 'a b'. Not used if positional parameters are present.
suffix: suffix to add to default tplot name in which to store sunpulse
data: thx_state_sunpulse (x = probe letter designation)
This suffix is expected on the names of the state data inputs.
Optional Inputs/Output parameters:
(if not present, then standard state tplot variable names will be used for i/o)
Input Parameters:
time_state: double precision array: times of data from state file
spinpha: spin phase from state file
spinper: spin period from state file
Output Parameters:
sunpulse: sunpulse times (times of zero spin phase)
sunp_spinper: spin period at time of each sunpulse.
Keywords:
sunpulse_name: string. If present, store sunpulse/spinperiod in tplot
variable with this name. Has no effect if probe keyword
is provided.
