Deep low-frequency radio observations of the NOAO Bootes field (Intema et al. 2011)

We observed the NOAO Bootes field with the GMRT at 153 MHz. This yielded an 11.3 square degree field, with a 26"x22" resolution and a central background noise level of 1 mJy/beam, rising to 2-2.5 mJy/beam towards the edge of the field. The extracted source catalog contains 598 sources, for which the completeness is estimated at ~92 percent for sources >10 mJy, while the contamination is estimated at <1 percent. We have obtained a spectral index α for 417 sources in the overlapping region with a WSRT 1.4 GHz map of de Vries et al. (2002), identifying 16 USS sources with α<-1.3.
