The following steps were carried out to obtain the final catalog.
Note that the finder is optimised to find point sources and rejects detections which appear in one channel only. 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.). The candidate list also contains a large number of hydrogen recombination line detections. Many galaxies, especially those with double or multi-horn profiles, also have several entries.
