SSWEIGHT Keyword not recognised by ImageIntegration

[akoenig]

Hi,
I've been using the new Subframe Selector, which is really great to write the Image weighting into the SSWEIGHT keyword.

When I try to integrated the files using the SSWEIGHT Keyword, PI comes up with the error message:
108 FITS keyword(s) extracted.
*** Error: E:/Moravian/M81-1/Registered/M81-1_Blue_0005_204939_90sec_-20C_a_c_cc_r.xisf: Nonexistent or invalid weight keyword 'SSWEIGHT'.
<* failed *>

I can see the SSWEIGHT keyword in the FITSHeader function and it is populated with a value. If I run the integration with a different keyword, such as NOISE00, the process runs normally.

I'm using the latest Version of PI.

So what am I doing wrong? I've attached a screenshot of the issue.

Thanks for your help.

Regards,
Allen

Hello Allen,

Weights should have positive values; try to revise the weighting function you are using.

Cheers and happy weighing

Thank you. That seems to have solved the issue. Once again the error was sitting in front of the screen
