Opening IRAF mosaics

Peter

I'm trying to open an IRAF mosaic, but astroimagej is not recognising the file as FITS.

Help?

Hi Peter,

Have you confirmed that the image will open in SAO DS9? If that works,
and it will not open in AIJ, the only way I can help is if you can
forward me the actual image file. You could email it to me at
karenacollins @@@ outlook dotdotdot com, or if it is too large to email,
we can work out a drop box or google drive exchange. In case the image
is sensitive/proprietary, it would be keep confidential.

Thanks for sending the example FITS file.

I don't see any way to open the current file format directly into AIJ. With a little google searching, I did see a special FITS WCS format for cameras with a array/mosaic of multiple cameras. AIJ does not support that mosaic format. Would it be possible to output the image segments from IRAF as individual single images with single headers?

I tried "Aladin" and it opens the file into 16 planes of images, whereas I could only see one image in DS9. Aladin also provides an option to "Export planes" to single image FITS files. I used that option and each of those single image FITS files opens into AIJ just fine.

I don't know how many images you are dealing with, but if it is only a few, maybe the Aladin option will work for you? If you have lots, maybe IRAF provides the same option and could be scripted??
