TGSSADR Source Catalogue
Listed in IVOA Registry (Virtual Observatory)
This service queries the catalogue of radio sources from the images of the TIFR GMRT Sky Survey (TGSS) Alternative Data Release (up to 1 deg square).
Description
This data release contains previously unpublished data from the TIFR GMRT Sky Survey (TGSS), which has been independently reprocessed. It includes continuum stokes I images of 99.5 percent of the radio sky north of -53° DEC (3.6π sr, or 90 percent of the full sky) at a resolution of 25“ x 25” north of 19° DEC and 25“ x 25” / cos(DEC-19°) south of 19°, and a median noise of 3.5 mJy/beam.
The extracted radio source catalog contains positions, flux densities, sizes and more for 0.62 Million sources down to a 7-sigma peak-to-noise threshold.
