Galaxy Profile Fitting with GIM2D
3 types of fit: Þ Separate bandpass (GIMFIT2D) Þ Simultaneous bandpass (C2GIMFIT2D) Þ Single bandpass, multiple images (MGIMFIT2D) Which one should I use ???? Answer: What are your goals and what data are you using?
2-bandpass bulge+disk profile fitting 2-bandpass profile fitting (with bulge/disk colors) Combines Data Quality Files Creates a galaxy model (+HII regions) Computes basic image moments of an object Creates simulations with HII regions Applies DQF mask to SExtractor segmentation image Calculates background parameters Front-end to MGIMFIT2D Bulge+disk profile fitting Computes residual image asymmetry indices Computes reduced chi-squared of best-fit model Creates "galaxy-free" version of input image Prepares input list for XGAL and CL script Contructs selection function Single-bandpass, single image simulations Provides the user with a simple graphical interface to review the status of the fitting process at any given iteration Multiple image profile fitting (NICMOS!!) Thumbnail image extraction (Science, segmentation and sigma)
