RE:Mars Images
Dear
Masatsugu,
Many thanks
for finding and telling me about the errors in my images. I have corrected
them. For the De, I will start using a
program that Jeff recommended called MAPOS. It is more accurate, according to
Jeff, although a bit cumbersome to use.
Sorry for the mistakes, but I appreciate your diligence in checking the
data.
Hope all is well with you. I am
getting tired of Mars!

Errors in Oct 14 images
Hi
All,
Masatsugu
Minami has pointed out errors in the Ls and Cms on my
14 October images. I have corrected these and enclosed the revised edition.
Sorry for the mistakes. The Curse of the Red Planet continues!
