... Virginia Kilborn's program gfinder was run on 388 luthered and edge-masked HIPASS cubes , covering the whole southern sky, over all 1024 channels (i.e. -1281 to 12741 km/s), with an HI peak flux cutoff of 60 mJy/beam. ... The large number of candidates is mostly due to artifacts generated in areas of strong continuum flux, mostly the Galactic Plane, (causing a baseline ripple), the HI emission in our Galaxy, and lots of interference (1408 MHz birdie, GPS etc.) ... Number of galaxies: . ... galaxies ...
