Table information for 'lolss.source_catalog'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This page provides public access to the LBA survey of HETDEX, as a single mosaic over the HETDEX field and associated catalogue, covering around 700 square degrees centered in the RA range 10h45m00s to 15h30m00s and DEC range 45d00m00s to 57d00m00s. 25,247 sources are detected and the rms noise level is around 4 mJy/beam at a resolution of 47 arcsec and an effective frequency of 54 MHz. The flux scale appears to be good based on a comparison with VLSS.

Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference arXiv:2102.09238 either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:
