PACS Point Source Catalog Definitions

Overview

To maximise the science return of the PACS data sets, a homogeneous Herschel/PACS Point Source Catalogue (HPPSC) was constructed from all the scan map observations. The catalogue enables a systematic and unbiased comparison of sensitivity across different Herschel fields that single programs will generally not be able to provide.
