... The gamma function [not the Gamma -- note upper-case G -- which is related to the factorial] is one of those insanely useful functions that after one finds out about it, one wonders ?why haven?t we been using this all the time?? It is defined only on the positive non-negative real line, is a highly flexible function that can emulate almost any kind of skewness in a distribution, and is a perfect complement to the Poisson likelihood. ...

The ATCA HI moment maps (below) show a large volume, about 40' x 40' in RA,DEC (not primary beam corrected for display purposes) and over a velocity range from 180 to 640 km/s. The velocity field shows that some of the extended gas clouds are in the foreground, most likely part of the Magellanic Stream. ...
