No FIRST data is available at 00 47 47.183 +25 14 27.96 (J2000).
Currently the FIRST survey covers two regions:

  North:     RA =  7.0h to 17.5h, Dec =  -8.0 deg to +57.6 deg
  South:     RA = 20.4h to  4.0h, Dec = -11.5 deg to +15.4 deg

The edges of the covered areas are slightly ragged in the north and
very ragged in the south (particularly north of Dec=+12.5 deg).
The northern coverage narrows in RA as it approaches the equator.
