NAME: thm_ui_check4spin 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_ui_check4spin, vname, vname_spin1, vname_spin2, history_out INPUT: vname = tplot variable name OUTPUT: vname_spin1 = the tplot variable containing the spin period. or spinras vname_spin2 = the tplot variable containing the spin phase or spindec history_out = a history string, if data needs loading KEYWORDS: rasdec = if set, return the variables for spinras, and spindec used for dsl <-> gse tranformations HISTORY: 26-feb-2007, jmm, jimm@ssl.berkeley.edu NOTES: The rest of the original GUI has been deprecated, but this routine is useful for a lot of the other THEMIS code. For now, it will live in common $LastChangedBy: jwl $ $LastChangedDate: 2014-01-24 16:22:37 -0800 (Fri, 24 Jan 2014) $ $LastChangedRevision: 14015 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/themis/deprecated/thm_ui/thm_ui_check4spin.pro $
