Sky distribution of galaxies in the SPRING sample in classes of the HI-deficiency parameter. The horizontal line at Dec = 36 deg traces the limiting pointing declination of the Arecibo dish. Grey circles stand for galaxies for which the H I content is unknown. Blue dots denote galaxies with H I_def ≤ 0.4, while red dots are for galaxies with H I_def > 0.4. The latter class is distributed consistently around (in) the Coma cluster and the Virgo cluster, with a small number of entries belonging to the A1367 cluster. It is noticeable that our knowledge of the H I properties of local galaxies in such an extended stretch of the sky depends on the availability of Arecibo data, which are limited to declination ≲ 36°.
