Abstract

New reduction tools are required to handle the increasing amount of photometric CCD data within a reasonable time. PODEX is an IDL based tool developed to optimize the time needed for extracting light curves out of photometric CCD data. The GUI based semi-automatic reduction tool provides the possibility to apply bias correction, flat fielding, and background modeling to the raw data. After extracting magnitudes even in crowded fields, a color--dependent extinction correction and a conversion to relative magnitudes is performed. The output of PODEX are completely reduced light curves of an arbitrary number of stars on the CCD images. As the conditions between various nights and observing runs change continuously and sometimes dramatically, full interactivity throughout the entire reduction procedure via a powerful graphical user interface is a big advantage over all black-box procedures known to us.
