Catalogue Descriptions

There are currently two ATLASGAL source catalogues; these have been produced using the Gaussclumps and SExtractor source extraction algorithms, which have been optimised to be sensitive to different angular scale structures. GaussClumps is preferred for the properties of the embedded compact objects while SExtractor is considered better for retrieving the global properties of the clumps. A brief outline of each catalogue and reference is provided below:

• Csengeri et al. (2014) - Gaussclumps: This catalogue is optimized for the parameters of small-scale embedded structures with background emission from molecular clouds removed. These structures correspond to cores in nearby- and clumps for the more distant regions. This is referred to as the GaussClump Source Catalogue (GCSC).
• Contreras et al. (2013) & Urquhart et al. (2014) - SExtractor: The first reference provides a detailed description of the source extraction and presents a catalogue of the inner Galaxy (i.e., 330^o < l < 21^o) while the latter is a research note presenting the catalogue for the rest of the survey area (i.e., 280^o < l < 330^o and 21^o < l < 60^o). This catalogue is optimized for larger-scale clump and cloud structures. This is referred to as the Compact Source Catalogue (CSC).
  

To avoid confusion between the two catalogue we use different naming convensions: The CSC names are constructed from the position of the peak emission taken to three decimal places and prefixed by the letters 'AGAL', while the GCSC names are constructed from the central source position taken to 4 decimal places and prefixed by the letter 'G'. A comparison between the two catalogues is presented in Csengeri et al. (2014). You are able to select which catalogue you wish to use in the cone search below.
