Advantage : Should produce more robust colors Disadvantage : Totally insensitive to color gradients in bulge and/or disk IRAF Parameters : in_list = "" List of input image(s) out_list = "" List of output image(s) sym_list = "" List of symmetrized image(s) res_list = "" List of residual image(s) msk_list = "" List of pixel mask image(s) sig_list = "" List of sigma image(s) logfile = "" Name of log file mdparfile = "" Name of parameter value file initparam = yes Determine parameters from image moments dosym = no Symmetrize input image ? dobkg = yes Recompute background parameters ? imscale = Image scale (arcsecond/pixel) psftype = "" PSF type psf_list = "" List of tinytim/user PSF image(s) c_abs = 0. Disk internal absorption coefficient (0-1) seeing = Seeing FWHM (arcseconds) bkgsig = Background sigma (ADU) nsamp = Number of parameter space samples ccdgain = CCD Gain (electrons/DU) metseed = Metropolis seed osamp = 5 Core oversampling factor (mode = "q") Strongly suggested : (1) First image in lists should be the better of the two (2) Use the same mask image for both colors and pick mask image of deeper science image
