Abstract:
In this paper we focus on 63 LoTSS data sets (2% of the total survey) in the region of the HETDEX Spring Field that were observed between 2014 May 23 and 2015 October 15. Each 8h observation was bookended by 10min calibrator observations (primarily 3C 196 and 3C 295) and the data are archived with a time resolution of 1s and a frequency resolution of 16 channels per 195.3kHz sub-band (SB) by the observatory. This catalogue contains 325694 radio sources, has a source density of 770 sources per square degree and a point-source completeness of 90% at an integrated flux density of 0.45mJy. (2 data files).
