Different dimensions for Ha and OIII extractions

Did an extract Ha and extract OIII integration, and normally that works out perfectly, but today the Ha came out 3011x3010 and the OIII 3010x3010. Shouldn't they be the same? That presents problems down the road, e.g. in cropping in PI, as I can no longer assume they're aligned identically.

Mmm, I normally load those extractions (when processed fully) in again to normalize those against each other (saving the frames). That already takes care of these things. Not sure why with the extraction alone it varies, I can ask Mabula about that. It does vary when going through processing a little.
