gwcs.coordinate_frames.CoordinateFrame
A coordinate frame for time axes.
Parameters: - axes_order : tuple or int
A dimension in the input data that corresponds to this axis.
- reference_frame :
object
The object to instantiate to represent the time coordinate. Defaults to
astropy.time.Time
. Use partial functions to customise theTime
instance.- reference_time :
astropy.time.Time
orNone
Reference time, the time of the 0th coordinate. If none the values of the axis are assumed to be valid times.
- unit : str or units.Unit instance
Spectral unit.
- axes_names : str
Spectral axis name.
- name : str
Name for this frame.
