SingleFrameGaapFluxConfig#

class lsst.meas.extensions.gaap.SingleFrameGaapFluxConfig(*args, **kw)#

Bases: BaseGaapFluxConfig, SingleFramePluginConfig

Config for SingleFrameGaapFluxPlugin.

Attributes Summary

`doMeasure`	whether to run this plugin in single-object mode (`bool`, default `True`)
`doOptimalPhotometry`	Perform optimal photometry with near maximal SNR using an adaptive elliptical aperture? This requires a shape algorithm to have been run previously.
`doPsfPhotometry`	Perform PSF photometry after PSF-Gaussianization to validate Gaussianization accuracy? This does not produce consistent color estimates.
`registerForApCorr`	Register measurements for aperture correction? The aperture correction registration is done when the plugin is instatiated and not during import because the column names are derived from the configuration rather than being static.
`scalingFactors`	List of factors with which the seeing should be scaled to obtain the sigma values of the target Gaussian PSF.
`sigmas`	List of sigmas (in arcseconds) of circular Gaussian apertures to apply on pre-seeing galaxy images.

Attributes Documentation

doMeasure#: whether to run this plugin in single-object mode (bool, default True)

doOptimalPhotometry#: Perform optimal photometry with near maximal SNR using an adaptive elliptical aperture? This requires a shape algorithm to have been run previously. (bool, default True)

doPsfPhotometry#: Perform PSF photometry after PSF-Gaussianization to validate Gaussianization accuracy? This does not produce consistent color estimates. If setting it to True, it must be done so prior to registering the plugin for aperture correction if registerForApCorr is also True. (bool, default False)

registerForApCorr#: Register measurements for aperture correction? The aperture correction registration is done when the plugin is instatiated and not during import because the column names are derived from the configuration rather than being static. Sometimes you want to turn this off, e.g., when you use aperture corrections derived from somewhere else through a ‘proxy’ mechanism. (bool, default True)

scalingFactors#: List of factors with which the seeing should be scaled to obtain the sigma values of the target Gaussian PSF. The factor should not be less than unity to avoid the PSF matching task to go into deconvolution mode and should ideally be slightly greater than unity. The runtime of the plugin scales linearly with the number of elements in the list. (List, default [1.15])

sigmas#: List of sigmas (in arcseconds) of circular Gaussian apertures to apply on pre-seeing galaxy images. These should be somewhat larger than the PSF (determined by scalingFactors) to avoid measurement failures. (List, default [0.7, 1.0])
