FITS header changed by drizzle inyegration

Jim Gianoulakis

I added drizzle integration into my work flow. My drizze integrated frames pixel size in the fits header is modified. In the non drizzled integration the pixel size is unchanged. The drizzled integrations are comparitively better but I cant plate solve. I must be doing something wrong. I used the image integration and drizzle integration configuration just as presented by NSG. Anybody seen this?

Thanks,

Jim

Jim,

Are you upsampling when you drizzle ( you must be) or just doing drizzle 1x1?

Yes, if you are upsampling you will need to adjust the parameters in ImageSolver.

Not knowingly. I accepted the parameters that NSG inserted. looking at drizzle Int. I see a scale parameter and it was set to 2. Set it to 1 and rerunning.

Thanks,

Jim

That was the issue, thanks. I did attempt to over-ride the imagesolver plate scale configuration but it reverted to what was in the FITS header
