Description
Constructs a widget for the entry of measures position values.
The allowed formats for user input are:
- The position reference frame may be chosen using the
left hand button. The two formats are WGS84 and ITRF (World Geodetic
System and International Terrestrial Reference Frame). The position
quantity values should be either longitude (angle), latitude(angle)
and height(length); or x,y,z (length). The allowed formats for
lengths and angles are described in the
quanta tool.
- An observatory location may be selected using the
ObservatoryList button under the spanner/wrench.
- The name of Glish variable or function that evaluates to a
position measure.
Note that changing the reference frame does not change the
values in the entry boxes. Instead, it defines the frame with the
currently specified values. If you wish to make a conversion, use the
measures position gui.
The options string can be used to specify vertically aligned
entries.
