Abstract
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.
