SourceTablePsfComponentsAction#

class lsst.meas.extensions.multiprofit.fit_coadd_multiband.SourceTablePsfComponentsAction(*args, **kw)#

Action to return PSF components from a SourceTable.

This is anticipated to be a deepCoadd_meas with PSF fit parameters from a measurement plugin returning covariance matrix terms.

Attributes Summary

`action_source`	Action to return whether the PSF fit was successful for a single source row (`PsfFitSuccessActionBase`, default `<class 'lsst.meas.extensions.multiprofit.fit_coadd_multiband.SourceTablePsfFitSuccessAction'>`)
`format`	Format for the field names, where {idx_comp} is the index of the component and {moment}is the name of the moment (xx, xy or yy, integral) (`str`, default `'modelfit_DoubleShapeletPsfApprox_{idx_comp}_{moment}'`)
`n_components`	Number of Gaussian components (`int`, default `2`)
`name_moment_integral`	Name of the integral (zeroth) moment (`str`, default `'0'`)
`name_moment_xx`	Name of the xx (2nd x-axis) moment (`str`, default `'xx'`)
`name_moment_xy`	Name of the xy (covariance term) moment (`str`, default `'xy'`)
`name_moment_yy`	Name of the yy (2nd y-axis) moment (`str`, default `'yy'`)

Methods Summary

`__call__`(source, args, *kwargs)	Call self as a function.
`get_integral`(moment_zero)	Get the total integrated flux from a zeroth moment value.
`get_schema`()	Return the list of columns required to call this action.

Attributes Documentation

action_source#: Action to return whether the PSF fit was successful for a single source row (PsfFitSuccessActionBase, default <class 'lsst.meas.extensions.multiprofit.fit_coadd_multiband.SourceTablePsfFitSuccessAction'>)

format#: Format for the field names, where {idx_comp} is the index of the component and {moment}is the name of the moment (xx, xy or yy, integral) (str, default 'modelfit_DoubleShapeletPsfApprox_{idx_comp}_{moment}')

name_moment_integral#: Name of the integral (zeroth) moment (str, default '0')

name_moment_xy#: Name of the xy (covariance term) moment (str, default 'xy')

Methods Documentation

__call__(source: Mapping[str, Any], *args: Any, **kwargs: Any) → list[Gaussian]#: Call self as a function.

static get_integral(moment_zero) → float#

Get the total integrated flux from a zeroth moment value.

The zeroth moment is simply the integrated flux divided by a constant value of 2*sqrt(pi).

Parameters#

get_schema() → list[str]#: Return the list of columns required to call this action.
