Although I'm the one that pointed to this way of doing things, I'd
like to assert that I don't think it is a good idea.  Duplicating the
same value into two different keywords was an engineering tradeoff
adopted for reasons more political than technical.

It should have been avoided, and would have if a data reduction
package in use had a means for translating keywords in the fashion
akin to that provided by IRAF.
