Description themis_rematm () - Perform atmospheric correction for THEMIS image using TES based training area. Requires THEMIS radcorred radiance image saved as “IXXXXXXXX.cub”.
Arguments and Return Values Arguments: A THEMIS image ID, TES pixels selected as training data from refine_tes_fp() function, mineral and atmosphere library. Return Value: A structure containing surface emissivity and the corresponding atmospheric opaicity spectrum
Usage Syntax: themis_rematm(id, training, [,minlib=STRING] [,atmlib=STRING] [,tes1=VAL] [,tes2=VAL]) 'id' - A string of THEMIS id in the form of IXXXXXXXX 'training' – selected TES pixels used as training data 'minlib' – surface mineral library. Default $DV_SCRIPTS_FILES/themis_atm_support/THEMIS_ATM_mineral_library.hdf 'atmlib' – 73 channel atmosphere library. Default $DV_SCRIPTS_FILES/themis_atm_support/TES_atmlib_73channel.hdf ‘tes1’ – start index for TES data selection ‘tes2’ – end index for TES data selection
