Abstract
A catalog of southern anomalous-velocity H I clouds at decl. < + 2° is presented. This catalog is based on data from the H I Parkes All-Sky Survey (HIPASS) reprocessed with the MINMED5 procedure and searched with a new high-velocity cloud-finding algorithm. The improved sensitivity (5 σ: δTB = 0.04 K), resolution (157prime;.5), and velocity range (-500 km s-1 < VLSR < +500 km s-1) of the HIPASS data result in a substantial increase in the number of individual clouds (1956, as well as 41 galaxies) compared with what was known from earlier southern data. The method of cataloging the anomalous-velocity objects is described, and a catalog of key cloud parameters, including velocity, angular size..
