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.
