The CORNISH Catalogue

Over 3,000 sources of radio emission were detected in the CORNISH images above a peak intensity of 7σ. This high reliability catalogue has been vetted for spurious sources and is presented below as an official data product. The data reduction and source finding procedures are described in the paper by Purcell et al. 2013, while details of the survey design are presented in the paper by Hoare et al. 2012.


Searching the CORNISH Catalogue

A cone search service is available for cross-matching the CORNISH catalogue with arbitrary sky-positions. Alternatively, the catalogue may be searched by name. Each entry is indexed by a unique name derived from its Galactic longitude and latitude, e.g., G029.9559-00.0168. Enter a full or partial source name in the box below to see a list of matching entries. The search string accepts the * wild-card to represent multiple characters.

Search for source names:
CORNISH Name:
Show Artefacts? No Yes
Show Errors? No Yes


As part of the catalogue validation process detections were manually inspected and notes recorded in the database. The text of these notes may be searched using the form below. For example, to find all sources with cometary shapes enter 'comet' as the search term.

Views of the CORNISH Catalogue

The 'View' buttons below link to the high-reliability CORNISH catalogue and a number of pre-defined subsets. Please note that catalogue is 'live', i.e., it is updated as new information becomes available and may differ from the originally published version.

The catalogue may be viewed in three formats:

  • HTML: A web-based catalogue containing links to the data and to detailed information on each source.
  • ASCII: A a plain-text, fixed-width version of the catalogue whose format is described in the file 'CORNISH_cat_format.txt'.
  • CSV: A comma-separated-variable file compatible with spreadsheet programs or dedicated analysis tools, e.g. the excellent Topcat table viewer. The column order is the same as the ASCII version.

Click on the 'View' buttons to display the catalogue in a new page.
