Contribution

It presents a new comprehensive catalogue of UV and optical sources from Swift UVOT data, including processing methods and detailed source information.

Findings

Contains over 6 million sources with UV and optical photometry.

Includes data quality flags and morphological information.

Over 2 million sources have multiple observations.

Abstract

We present the first Swift Ultraviolet/Optical Telescope Serendipitous Source Catalogue (UVOTSSC). The catalogue was compiled from 23,059 Swift datasets taken within the first five years of observations with the Swift UVOT. A purpose-built processing pipeline, based around the standard Swift processing tools, was employed. The catalogue contains positions, photometry in three UV and three optical bands, morphological information and data quality flags. In total, the catalogue contains 6,200,016 unique sources of which more than 2 million have multiple observations in the catalogue.
