Image Calibration with Overscan - How?

[dflipp]

I'm having trouble figuring out how to set up overscan correction for image calibration.  I've set the image and target regions to be the entire image area of my KAF-8300M (0, 0, 3326, 2504).  The source region is defined in the overscan to the right of the image area.  I always get an "Inconsistent overscan geometry" error.  I have attached a screen shot of my overscan config.

Any advice or a link to a tutorial would be greatly appreciated.

Thanks,
Dan

That looks OK to me assuming the overscan region is where you think it is.  What's the actual geometry of the FITS files coming from the camera/driver/acquisition software?  If they are smaller than 3391x2504 then I expect that would provoke an error.

I have an Apogee Alta U16M camera which has an image area of 4096x4096.  The FITS files are 4116x4096 in size (MaximDL Apogee driver with Digitize Overscan enabled) and the overscan region is the last 9 columns.  I use an image region of 0, 0, 4096, 4096 a source region of 4107, 0, 9, 4096 and a target region of 0, 0, 4096, 4096.

Cheers,
Rick.

Thanks, Rick.

The FITS files from my camera are 3452 x 2632.  The values for NAXIS1 and NAXIS2 in the header reflect these values as well so I don't understand why I keep getting the invalid geometry error.

No idea, however I have a guess. If you are using Masters integrated with a previous version of PI, why don't you try integrating them again in 1.8 RC3?

Saludos, Alejandro.
