D. Hartmann et al., STRAY-RADIATION CORRECTION AS APPLIED TO THE LEIDEN DWINGELOO SURVEY OF HI IN THE GALAXY/, Astronomy & Astrophysics. Supplement series, 119(1), 1996, pp. 115-151
This article describes the stray-radiation correction that was applied
to the HI observations of the Leiden/Dwingeloo survey of Hartmann & B
urton. This correction involved convolving the empirically-determined
antenna pattern with the measured all-sky HI distribution. The importa
nce of the correction is demonstrated and practice regarding its appli
cation described. The general algorithm used here is presented. The re
sults obtained with this algorithm are compared to those following fro
m other methods. The 0.07 K sensitivity level of the survey depends cr
itically on the success of the stray-radiation correction.
