HPPSC2 Catalog Definitions

Overview

The HPPSC2 project revisited all the photometric observations obtained by the PACS instrument on-board of the Herschel space observatory, using more advanced techniques than before, including machine learning techniques.

HPPSC2 includes a high-reliability and a rejected source catalogue for each PACS passband, i.e., at 70, 100, and 160 um. With the high-reliability catalogue, completeness in all bands is improved, especially at 70 um. At the same time, while the number of high-reliability detections decreased, the number of sources matching with existing catalogues increased, suggesting that the purity is also higher than before.
