FUNCTION: fu_fit2d(dat,ENERGY=en,ERANGE=er,EBINS=ebins,...) Select energy/angle range and perform functional fit to data (default Maxwellian) INPUTS: dat - data structure containing 2d data - e.g. "get_fa_ees, get_fa_ies, etc." KEYWORDS: NFITF integer optional number of functions for the fit, default = 1 FITF string optional function for the fit, default = maxwellian AUTO 0/1 if set, defaults are used and peak energy determined from the data ENERGY: fltarr(2), optional, min,max energy range for fit ERANGE: fltarr(2), optional, min,max energy bin numbers for fit EBINS: bytarr(na), optional, energy bins array for fit 0,1=exclude,include, na = dat.nenergy ANGLE: fltarr(2), optional, min,max pitch angle range for fit ARANGE: fltarr(2), optional, min,max angle bin numbers for fit BINS: bytarr(nb), optional, angle bins array for fit 0,1=exclude,include, nb = dat.ntheta BINS: bytarr(na,nb), optional, energy/angle bins array for fit 0,1=exclude,include LIMITS - A structure containing limits and display options. see: "options", "xlim" and "ylim", to change limits UNITS - convert to given data units before plotting F_UNITS - convert dat.data to given data units before passing to function "FITF" COLOR - array of colors to be used for each bin LABEL - Puts bin labels on the plot if set. SUMPLT - redraws the summed data and the fit after completion. MSEC - Subtitle will include milliseconds NOTES: This program still has bugs and may not weight the points properly !!!!! See "spec2d" for another means of plotting data. See "conv_units" to change units. See "time_stamp" to turn time stamping on and off.
