The GCL Globular Cluster List. Origins anyone?
I've been trawling through the long list of Globulars and I noted that many have an alternative designation GCLxxx. Can anyone (Glenc?) shed some light as to the origin of this catalogue? I cannot locate any info on it via Mr. Google.
e.g.:
NGC 104 (47 Tuc) is GCL 1
NGC 7492 appears to be the last GCL125
I have attached a list I've compiled myself, with some missing numbers also
