unit

named_arrays.unit(a, unit_dimensionless=None, squeeze=True)

Isolate the physical units associated with the given object.

If the array has no physical units, this function returns None.

Parameters:

• a (Any) – object to isolate the units of

• unit_dimensionless (None | float | UnitBase) – The unit to use for dimensionless objects.

• squeeze (bool) – If the result is an instance of named_arrays.AbstractVectorArray, and all the components are the same, simplify the result into a single astropy.units.Unit instance.

Return type:

None | UnitBase | AbstractArray

unit_normalized()

version of this function that by default returns astropy.units.dimensionless_unscaled instead of None if there is no unit associated with the given object.
