RE: Fits Headers Again

[Tom Droege <tdroege@veriomail.com>]

Arne,

Hmmm!  As I recall, you have advocated real time processing of the images 
and not saving raw images at all.  I am proposing saving the images in a 
form that tries to get them in a shape where they could be passed around as 
isolated entities.  i.e. without the log book.

Just trying to figure out the right way to do it.  I hope to have images 
with fits headers in a few days and will try passing them out as further 
distribution disks.  Then we will see what happens.

I think a first project for me will be to ask if someone will write a 
program to read an image and add WCS to it.  I assume that this is a simple 
script that I could do on my Linus machine which has both a read and write CD.
