Many entry fields permit sexagesimal entry (h:m:s.s or °:':"). You can easily spot such fields because the units label for an empty field will show hms or °'". Sexagesimal entry is flexible in that you can specify one to three fields, as you desire. As you enter enter data the units display will update to show you what is going on.
Position entry widgets assume that a single field is decimal hours or degrees (h.h or °.°) and two fields are hours (or degrees) and minutes (h:m.m or °:'.'). Entry rules are as follows:
Here are some examples:
Note: sexagesimal offsets and durations are entered in the same fashion, but a single field is decimal arc-seconds or seconds ('.' or s.s) and two fields are (arc) minutes and seconds (':"." or m:s.s).
