drizzling

[Guest]

Hello,

i wonder if you could help me: i'm working on WFPC2 files. i want to ad
d them with "crrej" but they are not aligned. i've been trying to run "drizzle"
to align them but i'm VERY confused!!
As far as i see drizzle works on one grou
p at a time, but WFPC2 images have 4 groups. So is there a way of combining the
four one group images (aligned by drizzle) into one four group image, again??

A
ny help would be greatly appreciated!

Regards
Evan Keane
