Hi,
I am having fits data, im reading it in this way.
img=readfits('file.fit',h)
Now if I do print,h it prints the header
a=avg(img(0:1023,0:1023),1) ; im averaging over 1024 rows
writefits,'file1.fit',a,h ; im writing into fits file
Now if I do print,h it prints the header were the COMMENT(the header
consists of 8 arrays out of which one array contains comment info)
part of the header of the original(file.fit) is different from the
one(file1.fit) which I got now.
Is there any way to retain all arrays of the header same before and
after writing to a new fits file.
regards
sid
