Mag#

class lsst.pipe.tasks.functors.Mag(col, **kwargs)#

Bases: Functor

Compute calibrated magnitude.

Returns the flux at mag=0. The default fluxMag0 is 63095734448.0194, which is default for HSC. TO DO: This default should be made configurable in DM-21955.

This calculation hides warnings about invalid values and dividing by zero.

As with all functors, a dataset and filt kwarg should be provided upon initialization. Unlike the default Functor, however, the default dataset for a Mag is 'meas', rather than 'ref'.

Parameters#

colstr

Name of flux column from which to compute magnitude. Can be parseable by the fluxName function; that is, you can pass 'modelfit_CModel' instead of 'modelfit_CModel_instFlux', and it will understand.

Attributes Summary

columns

Columns required to perform calculation.

name

Full name of functor (suitable for figure labels).
