Do we want to do anything at this time to signify whether we're producing the dem- or ellipsoid-version of sigma0? (sorry, this one still confuses me, so I'm not even 100% clear on which one is produced by default)

Should the description say whether it's dem vs ellipsoid sigma0?

Yeah I think I will add to the description here and add a logger.warning statement in the workfow to let the user know the sigma0 data is dem referenced, and ellipsoid referenced should be made using the incidence angle. Unfortunately it's not very clean... what do you think?

Confirming that this is no longer required because we're using the GA-fork version of the code?

Does this now need to be changed to "collection_number"? Or have you not made that change just yet?

collection_number logic will come in the next PR, just didn't want to make too many changes at once for y'all to review

dem_typeto be a single value or list of preferences. The code will then iterate through the preferences and if the preferred option has dem data it will be used. For example, preferencing the REMA_32 DEM for the Antarctic regionbackscatter_coventionat the top level. This enablesgamma0,sigma0andbeta0data to be created from the top
