Hipparcos / Tycho data now in more user friendly form

[John Murrell <JohnMurrell@compuserve.com>]

I beleive that you are using the Hipparcos / Tycho data as part of the
analysis pipeline for some of the TASS results. FYI the Hipparcos team have
just released a new CDROM containing Hipparcos / Tycho data in a more
easily usable form. I have copied the details from the Hipparcos Newsletter
below.
