NAME: thm_autoload_support PURPOSE: given a THEMIS tplot variable name, check to see if spin period and phase exist, for coordinate transformations, If they do not, load the state data for the appropriate time period CALLING SEQUENCE: thm_autoload_support, vname=vname, spinmodel=spinmodel, spinaxis=spinaxis, slp=slp, probe_in=probe, trange=[tmin, tmax], history_out=hist_string INPUT: OUTPUT: KEYWORDS: vname = tplot variable name probe_in: Specifies the probe name to load support data for (required for /spinmodel and /spinaxis) spinmodel: if set to 1, ensure spinmodel data is loaded and covers the requested time interval spinaxis: if set to 1, ensure state (spinras, spindec) data is loaded and covers the requested time interval slp: if set, ensure sun & moon data are loaded and cover the requested time interval trange: Specify a time range for which support data should be loaded (required if vname is not supplied) history_out = a history string, if data needs loading HISTORY: 2013-12-19: Adapted from thm_ui_check4spin by jwl NOTES: $LastChangedBy: jwl $ $LastChangedDate: 2014-06-12 10:12:12 -0700 (Thu, 12 Jun 2014) $ $LastChangedRevision: 15355 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/themis/state/thm_autoload_support.pro $
