Changeset 24419 for trunk/psModules/src/concepts/pmConceptsStandard.c

Timestamp:

Jun 15, 2009, 3:49:50 PM (17 years ago)

Author:

Paul Price

Message:

Only write sexagesimal coordinates if we're writing RA in hours and
Dec in degrees, otherwise we're liable to confuse people. Of course,
in every other case, we write decimal values, and then the user has
to check the format anyway. Fixes ticket 1264.
