TimeTableCoordinate#

class ndcube.extra_coords.TimeTableCoordinate(*tables, names=None, physical_types=None, reference_time=None)[source]#

A lookup table based on a Time, will always be one dimensional.

Parameters:

table (Time) – Time coordinates. Only one can be provided and must be 1D.
names (str or list of str) – Custom names for the components of the SkyCoord. If provided, a name must be given for each component.
physical_types (str` or list of str) – Physical types of the components of the SkyCoord. If provided, a physical type must be given for each component.
reference_time (Time, optional) – The reference time of the time coordinates. Default is first time coordinate in table input.

Attributes Summary

`frame`	Generate the Frame for this LookupTable.
`model`	Generate the Astropy Model for this LookupTable.
`n_inputs`	Number of pixel dimensions in this table.

Methods Summary

`interpolate`(new_array_grids, **kwargs)	Interpolate TimeTableCoordinate to new array index grids.
`is_scalar`()	Return a boolean if this coordinate is a scalar.

interpolate(new_array_grids, **kwargs)[source]#

Interpolate TimeTableCoordinate to new array index grids.

Kwargs are passed to underlying interpolation function.

Parameters:: new_array_grids (array-like) – The array index values at which the the new values of the coords are desired. A grid must be supplied for each pixel axis (in array-axis order). All grids must be the same shape.
Returns:: new_coord (TimeTableCoordinate) – New TableCoordinate object holding the interpolated coords.

is_scalar()[source]#

Return a boolean if this coordinate is a scalar.

This is used by MultipleTableCoordinate and ndcube.ExtraCoords to know if the dimension has been “dropped”.
