Abstract

We present a software package performing object detection, photometry and star-galaxy classification specially developed to cope with multi-band imaging data as are common in modern extragalactic imaging surveys, and to be modular and therefore easily adaptable to specific needs. Specifically, the package is designed to work under conditions of inhomogeneous background noise across the detection frame, and, additionally, perform accurate aperture photometry in image sets not sharing a common coordinate system or pixel scale as is often the case in present-day extragalactic survey work. The package has been used for the MUNICS survey. The package is described in detail and its performance is compared to existing software using real imaging data.
