As of DM-15244 and in aid of RFC-333 all existing afw table fields that had suffix
Sigma now have suffix
Err. This includes centroids, fluxes and aperture corrections. I also changed argument and variable names for consistency.
Existing persisted tables can still be read: for each field whose name ends in
Sigma an alias is made that ends in
Err. In order to implement this, I incremented the
VERSION constant in
afw/table/SchemaImpl.h from 1 to 2.
