... This paper describes the capabilities of GIM2D, an IRAF package for the quantitative morphology analysis of distant galaxies. GIM2D automatically decomposes all the objects on an input image as the sum of a S?rsic profile and an exponential profile. ... GIM2D (Galaxy IMage 2D) is an IRAF package written to perform detailed bulge/disk decompositions of low signal-to-noise images of distant galaxies. ... The segmentation image is used by GIM2D to deblend galaxy images. ... Create a residual image. ...

NICMOS Camera 3 is being used in parallel mode to observe galactic fields at both high and low galactic latitudes. ... Most of the fields are at high galactic latitude; as Figure 1 shows, only 8 pointings are within |b| = 10 o , i.e. the galactic disk. Figure 1: NICMOS parallel fields distribution in galactic latitude. ... Figure 6 ). ...

IRAF/STECF 2-D spectrum point source / background decomposition package . ... The general problem is one of spectral decomposition - of separating the spectra of the point sources from the background. ... The STECF IRAF layered package "specres" provides two tasks to extract point source spectra from 2-D images (either longslit, multislit or cross-dispersed) and decompose the full background over the image. ... A Point Source Function spectrum image is required as a 2-D spectrum. ...
