Arp 299 (IC 694 + NGC 3690) is one of the nearest examples of interacting galaxies with a high infrared (IR) luminosity ( , for the assumed distance Mpc), close to the limiting value for ultraluminous IR galaxies. We present HST /NICMOS observations taken with all three cameras. ... We have presented HST /NICMOS observations of the interacting system Arp 299 (IC 694 + NGC 3690). ...

... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...

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. ...
