TRAMISUBOO ivo://nasa.heasarc/tramisuboo NASA/GSFC HEASARC Williams et al. 2026-10-02 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source This table contains results from wide-area, deep, high-resolution 153-MHz GMRT observations of the NOAO Bootes field, adding to the extensive, multi-wavelength data of this region. The observations, data reduction, and catalog construction and description are described in the reference paper. The seven pointings (listed in Table 2 of the reference paper) produced a final mosaic covering 30 square degrees with a resolution of 25". The rms noise is 2 mJy/beam in the center of the image, rising to 4-5 mJy/beam at the edges, with an average of 3 mJy/beam. Seventy-five per cent of the area has an rms < 4 mJy/beam. The extracted source catalog contains 1289 sources detected at 5 sigma at flux densities between 4.1 mJy and 7.3 Jy, of which 453 are resolved. The authors estimate the catalogue to be 92% reliable and 95% complete at an integrated flux density limit of 14 mJy. The flux densities and astrometry have been corrected for systematic errors. In their paper, the authors calculate the differential source counts which are in good agreement with those in the literature and provide an important step forward in quantifying the source counts at these low frequencies and low flux densities. The GMRT 153-MHz sources have been matched to the 1.4-GHz NVSS and 327-MHz WENSS catalogs and spectral indices were derived. The source catalog presented here is derived from seven 4 hour pointings with the GMRT at 153 MHz, centered on the NOAO Bootes field. The resulting 30 square degree image has a central noise level of 2 mJy/beam and a resolution of 25". This table contains entries for all 1289 detected 153-MHz radio sources as well as for the 160 Gaussian components of the 77 sources (71 doubles and 3 triples) which could be fit by multiple Gaussian components, making a total of 1449 entries.
