Attributes Documentation

axes_type¶

An upcase string describing the type of the axis.

Known values are "SPATIAL", "TEMPORAL", "STOKES", "SPECTRAL", "PIXEL".

axis_physical_types¶: The UCD 1+ physical types for the axes, in frame order.

reference_frame¶

The reference frame of the coordinates described by this frame.

This is usually an Astropy object such as SkyCoord or Time.

world_axis_object_classes¶

The APE 14 object classes for this frame.
