Abstract

We present the results of a radio continuum survey at 21 cm wavelength of the Galactic plane between 955 240° and -4° ≤ b ≤ +5° with the Effelsberg 100-m telescope. The data have been absolutely calibrated by using the Stockert northern sky survey at the same wavelength. This survey complements the Effelsberg 21 cm Galactic plane survey for l ≤ 955 by Reich et al. (1990a). The results are presented as contour maps with a sensitivity of 100 mK T_B at an angular resolution (HPBW) of 94. In addition we extend the list of compact sources given by Reich et al. (1990a) by 1830 new entries. These sources have peak flux densities exceeding 160 mK T_B (or 79 mJy/beam area) and apparent sizes of less than 16.
