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.
