| Abstract: |
In this paper we demonstrate the resaults of reducing galaxy group images using THELI (Erben & Schirmer, 2005), an image processing
pipeline. The observation was
performed using the INT 2.54m telescope WFC camera in U, B, R and I band.
Science frames mostly consist of Hickson Compact Galaxies (HCGs). Emphasis is mainly placed on
photometric calibration which is of great interest to us due to our scientific
case. Based on the cross-association of the extracted catalog against a
reference catalog of stellar magnitudes, zeropoint calibration is performed. |
