NAME: spd_ui_coordinate_systems PURPOSE: This object exists for two purposes: 1) Maintain the list of coordinate systems used throughout SPEDAS in a single location 2) Encapsulate the methods that produce coordinate system lists for different contexts, e.g., the verify data panel, load data panel, data processing panel, etc. Both are ultimately for code maintenance KEYWORDS: METHODS: makeCoordSysList: creates and returns a list of valid coordinate systems makeCoordSysListForSpinModel: creates and returns a list of valid coordinate systems that don't require spin model variables to be loaded makeCoordSysListForTHEMIS: creates and returns a list of valid THEMIS-centric coordinate systems ('dsl', 'ssl', 'spg') makeCoordSysListForTHEMISReqPos: creates and returns a list of valid THEMIS coordinate systems that require position data to be transformed to/from EXAMPLES: To make a simple list of general purpose coordinate systems: SPEDAS> coordSysObj = obj_new('spd_ui_coordinate_systems') ; create the object SPEDAS> print, coordSysObj->makeCoordSysList(/uppercase) ; make the list DSL SSL SPG GSM AGSM GSE GEI SM GEO MAG SEL SSE SPEDAS> print, coordSysObj->makeCoordSysList(/uppercase, /include_none) ; include N/A N/A DSL SSL SPG GSM GSE GEI SM GEO MAG SEL SSE SPEDAS> print, coordSysObj->makeCoordSysList(/uppercase, /include_none, /include_all) ; includes 'N/A' and 'ALL' N/A DSL SSL SPG GSM GSE GEI SM GEO MAG SEL SSE ALL SPEDAS> obj_destroy, coordSysObj ; delete the object NOTE: All coordinate system lists exist in this object's constructor, with pointers to the lists in the objects state structure Changes to this object should be reflected in the corresponding test procedure, spd_ui_test_coordinate_systems_obj $LastChangedBy: egrimes $ $LastChangedDate: 2014-09-25 16:30:09 -0700 (Thu, 25 Sep 2014) $ $LastChangedRevision: 15868 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/spedas/gui/objects/spd_ui_coordinate_systems__define.pro $
