Hi everyone,I'm new to this software and get it successfully installed on my Ubuntu machine and everything seems to work fine. I can login and use things like [b:cefaafbf7b]STSDAS[/b:cefaafbf7b]. Furthermore, I'm not a astronomer I am a computer scientist and need to use raw images of hubble for some image processing things (can't mention it yet, still under investigation and development). Besides, I'm not a native speaker, so please apologize my english mistakes
I want to combine HST WFPC2 images with [i:cefaafbf7b]wmosaic[/i:cefaafbf7b] to one single image and further combine - if possible - several wavelength images to a color image with some corrections like shift, etc. (all in 16 or 32-bit precision). Currently, I downloaded images (Boomerang nebula) for the HST archive[code:1:cefaafbf7b]u47b0301b_asn.fits
u47b0301r_c0f.fits
u47b0301r_c1f.fits
u47b0301r_c3t.fits
u47b0301r_shf.fits
u47b0301r_trl.fits
u47b0301r_x0f.fits
u47b0302r_c0f.fits
u47b0302r_c1f.fits
u47b0302r_c3t.fits
u47b0302r_shf.fits
u47b0302r_trl.fits
u47b0302r_x0f.fits
[/code:1:cefaafbf7b]Using [b:cefaafbf7b]DS9[/b:cefaafbf7b] I can open the *c0f* files. If I try to open it with [i:cefaafbf7b]wmosaic[/i:cefaafbf7b], I get the following error:[code:1:cefaafbf7b]wfpc> wmosaic u47b0301r_c0f.fits test.fits
ERROR: input image u47b0301r_c0f.fits is not 2-D
[/code:1:cefaafbf7b]
(Same error with image [i:cefaafbf7b]u47b0301r_c0f.fits[0][/i:cefaafbf7b])If I check the file with [i:cefaafbf7b]imheader[/i:cefaafbf7b] I get:
[code:1:cefaafbf7b]wfpc> imheader u47b0301r_c0f.fits[0]
u47b0301r_c0f.fits[0][800,800,4][real]:
[/code:1:cefaafbf7b]After some internet search I found lots of examples using [i:cefaafbf7b]hhh[/i:cefaafbf7b] files. Yet, if I convert the images to hhh it doesn't work either:[code:1:cefaafbf7b]wfpc> rfits u47b0301r_c0f.fits 0 out.hhh
File: u47b0301r_c0f.fits -> out.hhh size=800x800x4
bitpix=-32 scaling=none pixtype=real
Warning: RFT_PUT_IMAGE_LINE: Error writing FITS data
Warning: FITS extensions may be present
[/code:1:cefaafbf7b]The file exists, but doesn't work with [i:cefaafbf7b]wmosaic[/i:cefaafbf7b], too:[code:1:cefaafbf7b]wfpc> wmosaic out.hhh other
ERROR: input image out.hhh is not 2-D
[/code:1:cefaafbf7b]
Does anybody have any clue what it could be? Is it also possible to combine several different-wavelength images to a colored one?Best regards
Andreas
