Image reduction pipeline for the detection of variable sources in highly crowded fields
Claus A. Goessl, Arno Riffeser
We present a reduction pipeline for CCD (charge-coupled device) images which was built to search for variable sources in highly crowded fields like the M31 bulge and to handle exte…
