Search for Extended Sources in the Images from Chandra X-Ray Observatory Advanced CCD Imaging Spectrometer.

VOLKOV I. and KARGALTSEV O.

Abstract (from CDS):

We present a convenient tool (ChaSES) which allows to search for extended structures in Chandra X-ray Observatory Advanced CCD Imaging Spectrometer images. The tool relies on DBSCAN clustering algorithm to detect regions with overdensity of photons compared to the background. Here we describe the design and functionality of the tool which we make publicly available on GitHub. We also provide online extensive examples of its applications to the real data.
