GMRT4F150M - Giant Metrewave Radio Telescope Field I 150-MHz Radio Source Catalog
The authors have observed FIELD I in GMRT Time Allocation Committee (GTAC) cycle 15 in 2008 January, whereas FIELD II and FIELD III were observed in cycle 17 during 2010 February. These target fields were selected at high Galactic latitudes (b > 10o) which were up at night time during the GTAC cycles 15 and 17, and which contain relatively few bright sources (>= 0.3 Jy) in the 1400 MHz NRAO VLA Sky Survey (NVSS). Finally, FIELD IV was observed in cycle 8 (2005 June). Full details of these 4 observations are given in Table 1 of the reference paper.
This table contains the 150-MHz source catalog for the most sensitive observation, namely the 9.8-hour observation of Field I (centered on J2000.0 RA and Dec of 5h 30m 00s, +60o 00' 00"), which was made on 2008 January 8.

The J2000.0 position-based designation of the 150-MHz source, viz. '[GPB2012] JHHMMSS.s+DDMMSS.s'. The HEASARC has replaced the 'GMRT' prefix used in the original paper (this usage is deprecated by the Dictionary of Nomenclature of Celestial Objects) with the '[GPB2012]' prefix standing for the first 3 authors of the paper (Ghosh, Prasad, Bharadwaj) and the date of publication (2012).

The Declination of the GMRT source in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 0.01 arcseconds in the original table.
