AngularSeparation

class lsst.analysis.tools.actions.vector.AngularSeparation(*args, **kw)

Bases: VectorAction

Calculate the angular separation between two coordinate positions.

Attributes Summary

decKey_A	Dec coordinate for position A (str, default 'coord_dec')
decKey_B	Dec coordinate for position B (str, default 'coord_dec')
outputUnit	Output astropy unit (str, default 'milliarcsecond')
raKey_A	RA coordinate for position A (str, default 'coord_ra')
raKey_B	RA coordinate for position B (str, default 'coord_ra')

Methods Summary

__call__(data, **kwargs)	Call self as a function.
getInputSchema()	Return the schema an AnalysisAction expects to be present in the arguments supplied to the __call__ method.

__call__(data: MutableMapping[str, ndarray[Any, dtype[_ScalarType_co]] | Scalar | HealSparseMap | Tensor | Mapping], **kwargs) → ndarray[Any, dtype[_ScalarType_co]]

Call self as a function.

getInputSchema() → Mapping]]]

Return the schema an AnalysisAction expects to be present in the arguments supplied to the __call__ method.

Returns:
