cds-question@unistra.frsurveysmolecular-cloudsradio-sourcesWe present observations of three active sites of star formation in the Taurus molecular cloud complex taken at 323 and 608MHz (90 and 50cm, respectively) with the Giant Metrewave Radio Telescope (GMRT). Three pointings were observed as part of a pathfinder project, targeted at the young stellar objects (YSOs) L1551 IRS 5, T Tau and DG Tau (the results for these target sources were presented in a previous paper). In this paper, we search for other YSOs and present a survey comprising of all three fields; a by-product of the large instantaneous field of view of the GMRT. The resolution of the survey is of order 10 arcsec and the best rms noise at the centre of each pointing is of order 100{mu}Jy/beam at 323MHz and 50{mu}Jy/beam at 608MHz. We present a catalogue of 1815 and 687 field sources detected above 5{sigma}_rms_ at 323 and 608MHz, respectively. A total of 440 sources were detected at both frequencies, corresponding to a total unique source count of 2062 sources. We compare the results with previous surveys and showcase a sample of extended extragalactic objects. Although no further YSOs were detected in addition to the target YSOs based on our source-finding criteria, these data can be useful for targeted manual searches, studies of radio galaxies or to assist in the calibration of future observations with the Low-Frequency Array towards these regions.2016MNRAS.462.2904Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/462/2904CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/332 : c2d Spitzer final data release (DR4) (Evans+, 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/A+A/468/353 : XMM-Newton Extended Survey of Taurus (Guedel+, 2007)J/ApJ/801/91 : Gould's Belt Very Large Array survey.
