Catalogues of Emission in HOPS

The HOPS catalogues specify regions of contiguous emission in the l-b-v data-cubes. Individual clouds which overlap in any dimension are detected as a single entity. The authors have made no attempt to separate cloud-components in the manner of Clumpfind or Fellwalker, for example.

The catalogues are offered below in plain-text format as comma seperated variable files (CSV). The authors recommend the excellent TOPCAT software to view, visualise and cross-match the catalogues with other source-lists. Choose 'CSV' from the format menu when loading the table.

Notes:
The catalogue of H2O masers offered above is a catalogue of emission detected with Duchamp. It is separate to the catalogue of H2O maser positions published in the first HOPS paper, which was created using the alternative HOPSFind method. All maser sites have been re-observed using the ATCA and this new catalogue supersedes the older catalogues.

Kvis annotation files (.ann) are also available for download above. The centroid position is plotted as a green cross, the brightness-weighted position as a magenta cross and the peak voxel position as a blue cross. Circles illustrate the equivalent radius of the emission.

Finally, the published versions of the NH3 (1,1) and (2,2) catalogues are available as a dump-file from a MySQL database here. To use you must create your own database on a local MySQL server and issue the command:
mysql -u UserName -pPassword DBname < hopsSQLdb.sql.
The NH3 (1,1) and (2,2) catalogues also include distance estimates and artefact flags.

======================================
Last updated 18-May-2012 by C. Purcell

This file describes the ASCII catalogue of detected emission sources in the
HOPS dataset. Each file contains the catalogue for a single molecular
transition and is in comma-separated-variable (CSV) format. Comments
are prefaced with a '#' and the first row contains the column names as
follows:
