The FITS extension header constructed from the ReadMe file of ReadMe

The data files can be automatically transformed into FITS: the above figure shows the ascii table extension header generated from the description file shown in Chapter 3. Files can be copied directly in this format with the cdsclient routines. This set of programs also includes for instance an access to the 1.1 version of the Guide star catalogue (findgsc) as well as a few other utilities related to the /Cats.htmlCatalogue Service or SIMBAD at CDS.

The transformation to FITS is made directly in the CDS ftpd server at the Internet Node cdsarc.u-strasbg.fr (detailed documentation on the CDS ftpd server).
