Procedure: thm_get_fft_cal_pars Purpose: Given the signal source, and begin and end of the time interval, return the FFT RAW->PHYS transformation parameters. Calling Sequence: thm_get_fft_cal_pars, tbeg, tend, fft_sel, nbins, cal_pars=cal_pars Arguements: tbeg, tend DOUBLE, time in seconds since THEMIS epoch. fft_sel INT, FilterBank source selection indicator. nbins, INT, number of frequency bins in spectrum (16, 32, 64). cal_pars STRUCT, see Notes below for elements. Notes: -- use of TBEG and TEND for time-dependent calibration parameters is not currently implemented! -- E-field gains and units are for actual deployed boom lengths (CDE). -- Elements of cal_pars are as follows: $LastChangedBy: jimm $ $LastChangedDate: 2007-11-16 12:28:13 -0800 (Fri, 16 Nov 2007) $ $LastChangedRevision: 2043 $ $URL $
