What to do if the CD-Rom does not work.

Please Note: (2004/03/10) We have restored the web page to serving multi-extension FITS files, rather that the simple FITS as included on the CD-Rom. Please let us know if you want the simple FITS served from here too and we will endeavour to impliment a mechanism for choosing your data format.
