MagDiff¶
- class lsst.analysis.tools.actions.vector.MagDiff(*args, **kw)¶
Bases:
VectorAction
Calculate the difference between two magnitudes; each magnitude is derived from a flux column.
Notes
The flux columns need to be in units (specifiable in the fluxUnits1 and 2 config options) that can be converted to janskies. This action doesn’t have any calibration information and assumes that the fluxes are already calibrated.
