Re: [guide-user] crossing the meridian

Kevin Cooper May 9, 2001

Hi Brian,

From my and a friend of mine's experience, Guide will not point well
after changing from one side of the pier to the other. Adding stars on
the second side results in the pointing not giving sensible pointing at
all. If we wish to change sides, we clear the ALIGN.DAT file and re-do
the alignment on the other side.

Do you have the ALIGNER.EXE program? It will clear the ALIGN.DAT file
for you. It's available from the Project Pluto site.
