Hi Markus,

At present, I don't have a copy of USNO-B1.0, so I've not revised
Guide to use it. (The data is provided on an 80 GByte hard drive.)

Dunno what other catalogs you might mean. If you've an interest in
UCAC-2, the method for displaying that catalog is described at

http://www.projectpluto.com/update8.htm#ucac2_display

The other "mega-catalogues", such as GSC-2.2 and 2MASS, are not
(to my knowledge) being distributed, other than via Internet.
