Abstract:
We present deep, high-resolution radio interferometric observations at
153MHz to complement the extensively studied NOAO Bootes field. We
provide a description of the observations, data reduction and source
catalog construction. From our single pointing GMRT observation of ∼12
hours we obtain a high-resolution (26"x22") image of ∼11.3 square
degrees, fully covering the Bootes field region and beyond.
Description:
The source catalog presented here is derived from a ∼12 hour single
pointing with the GMRT at 153 MHz, centered at the NOAO Bootes field.
The resulting 11.3 square degree image has a central noise level of
∼1mJy/beam and a resolution of 26"x22".
