Image Integration Fails to use FITS Keyword

[dhb2206]

I've had a couple of goes at bringing in a keyword from the new subframe selector process, but integration fails to pick these up. See screenshot - keyword is embedded but an error is triggered.

If I can see well from your screenshot, the FITS Keyword name has lowercase characters ("MyWeight" ?), which is different from the keyword entered at the ImageIntegration keyword field (MYWEIGHT). Maybe that discrepancy is causing the error. Negative weight values can also cause this error.

Ah, thanks, it'll be the negative weight values causing the problem then.
