Re: [guide-user] Using Tycho-2 CD
Ray Shapp Aug 27, 2002
Hi Kevin,
Thanks for the info on loading Tycho-2. Now I have some related questions:
1. The Tycho info on the Guide 8 Disk 1 is probably selectively edited. I am
guessing this is so because the data file on the USNO Tycho-2 CD is 515 Mb,
whereas the LG_TYCHO.LMP file on the Guide 8 Disk 1 is only 91Mb.
2. Is there any way to use the data directly from the USNO Tycho-2 CD without
loading the (probably edited) version off Guide 8 Disk 1?
3. Is there any way to delete the Guide version of the Tycho data from my
hard disk and get Guide 8 to recognize that it's no longer loaded? I used
Windows explorer to delete the LG_TYCHO.LMP file from the GUIDE8\HIPP folder
on my hard disk, but when I re-open the Extras menu item, the entry for
"Tycho-2 (94)Mbytes)" is still marked with an asterisk.
Thanks for the help.
