Photometry of overlapping galaxy pairs

Galaxy pair is a kind of self-gravitational system, which contains two member galaxies. Because of simplest configuration, galaxy pairs are very useful to study the interaction effect, such as merge, tidal force, dynamic fiction. However, projected effect often causes overlapping in galaxy pairs, especially in compact pairs. That seriously biases photometric parameters due to comtamination of each star light and obstructs further study about galaxy pairs. So how to get rid of overlapping influence has become a very important task. More accurate photometry of overlapping galaxy pairs will be more helpful for future research.
