In addition, the conversion between decimal degrees and DMS is trivial. If the catalog uses decimal degrees, it can be easily converted to DMS for user friendly displays. This point negates Con(2) under Decimal Degrees. I'm not throwing my two cents either way, just providing a few additional thoughts. So long as the data is in its own subfield and it doesn't need to be parsed out of other textual data, then either format can be used effectively. Andy.
