ADC_Keywords: Magellanic Clouds ; Interstellar medium ; H I data Keywords: Galaxy: halo - intergalactic medium - ISM: H I - Local Group - Magellanic Clouds Abstract: A catalog of southern anomalous-velocity HI clouds at δ<+2° is presented. This catalog is based on data from the HI Parkes All-Sky Survey (HIPASS) reprocessed with the MINMED5 procedure and searched with a new high-velocity cloud-finding algorithm. The improved sensitivity (5σ: ΔTB=0.04K), resolution (15.5'), and velocity range (-500km/s<VLSR<+500km/s) 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, peak column density, total flux, position angle, and degree of isolation, is presented.

Note (1): Consisting of a prefix followed by the Galactic longitude, Galactic latitude, and Local Standard of Rest velocity. HVC = filamentary features and their sub-structures which are organized into large high-velocity cloud complexes; CHVC = features satisfying the criteria of compact, isolated, high-velocity clouds (as discussed in Section 2.4); :HVC = clouds which could not be unambiguously classified as a CHVC; GLXY = galaxies cataloged in either the LEDA or the NED databases or visible in Digital Sky Survey (DSS) data. Note (2): Where VGSR = 220cos(b)sin(l) + VLSR. Note (3): Where VLGSR = VGSR - 62cos(l)cos(b) + 40sin(l)cos(b) - 35sin(b), following Braun & Burton (1999A&A...341..437B). Note (4): From the spectrum which passes through the peak brightness temperature pixel of the object. Those values below 26km/s (the velocity resolution) should be thought of as having 26km/s as the upper limit. Note (5): Based on the total number pixels assigned to an object times the area of a 4'x4' pixel. Note (6): If the object has a clearly discernable optical counterpart it is followed by ``(A)'', if it does not, and has a GSR velocity exceeding 300km/s, it is followed with ``(B)''.
