Description:
The fits files contain the observed and interpolated data of a survey
of linear polarization (Stokes U and Q) at 1.4GHz, obtained with the
25.6-m telescope of the Dominion Radio Astrophysical Observatory in
Canada. The angular resolution is 36 arcmin. The data are corrected
for ground radiation and tied to absolute determinations of zero
levels. Survey observations were carried out by drift scanning the sky
between -29° and +90° declination. The fully Nyquist- sampled
drift scans were observed in steps of 0.25° to about 2.5° in
declination. The rms noise is 12mK in Stokes U and Q.
