Creating mosaics using WCS

kstassun wrote on Nov 27, 2006

I am trying to figure out the best way to create a mosaic from several fits images (they are 2MASS images downloaded from IRSA). The images already have complete WCS headers so I don't need to determine a plate solution or match objects to astrometric catalogs or anything like that. I just need to 'paste' the images together based on their WCS, and end up with a final image that itself has a correct WCS. Does IRAF have this capability, or is there an external package that can do this? I would think that the 'mscred' package can do this, but it appears to be specifically for processing MEF images and solving dithering, etc.

Frank may comment on how to do this in MSCRED, but as a first pass, see Example 3 of the WREGISTER task help page.

Cheers,
