Deep, high-resolution survey at 74MHz
Listed in IVOA Registry (Virtual Observatory)
We present a 74MHz survey of a 165deg^2^ region located near the north Galactic pole.
Description
This survey has an unprecedented combination of both resolution (25" FWHM) and sensitivity ({sigma} as low as 24mJy/beam). We detect 949 sources at the 5{sigma} level in this region, enough to begin exploring the nature of the 74MHz source population.
We present differential source counts, spectral index measurements, and the size distribution as determined from counterparts in the high-resolution FIRST 1.4GHz survey, Cat. <VIII/71>.
