Dump the `FieldOptions` structure to a reference file #91

Closed tjgalvin closed 1 week ago

tjgalvin commented 2 months ago

All options related to the processing of a field are stored in a FieldOptions structure that is passed into the prefect workflow.

This should be dumped to a dumb file in the output science folder for record keeping.

This is actually more important than first initially thought.

This should be done promptly as the holography needs to also be rotated. There are a number of implicit assumptions that will have to be made regarding the orientation of the third-axis and footprint when the holography data were formed.

We will need to provide the alpha (in rad) parameter to the linmos parset, which is the differential rotation between the science field's footprint PA and the holography footprint PA.

We can (should) be able to get the original third-axis rotation from the original MSs (or from the fixms corrected MSs after a patch and an appropriate column name change). Then we will just have to assume the footprint rotation is fixed, and the holography orientation (third-axis and footprint) remain fixed.

Not nearly as important as first thought.
