AssembleCoaddConfig¶

class lsst.pipe.tasks.assembleCoadd.AssembleCoaddConfig¶

Bases: lsst.pipe.tasks.coaddBase.CoaddBaseConfig

Configuration parameters for the AssembleCoaddTask.

Notes

The doMaskBrightObjects and brightObjectMaskName configuration options only set the bitplane config.brightObjectMaskName. To make this useful you must also configure the flags.pixel algorithm, for example by adding

config.measurement.plugins["base_PixelFlags"].masksFpCenter.append("BRIGHT_OBJECT")
config.measurement.plugins["base_PixelFlags"].masksFpAnywhere.append("BRIGHT_OBJECT")

to your measureCoaddSources.py and forcedPhotCoadd.py config overrides.

`maskPropagationThresholds`	Threshold (in fractional weight) of rejection at which we propagate a mask plane to the coadd; that is, we set the mask bit on the coadd if the fraction the rejected frames would have contributed exceeds this value.

Methods Summary

`setDefaults`()	Derived config classes that must compute defaults rather than using the Field defaults should do so here.
`validate`()	!Validate the Config; raise an exception if invalid

Methods Documentation

setDefaults()¶: Derived config classes that must compute defaults rather than using the Field defaults should do so here. To correctly use inherited defaults, implementations of setDefaults() must call their base class’ setDefaults()

validate()¶

!Validate the Config; raise an exception if invalid

The base class implementation performs type checks on all fields by calling Field.validate().

Complex single-field validation can be defined by deriving new Field types. As syntactic sugar, some derived Field types are defined in this module which handle recursing into sub-configs (ConfigField, ConfigChoiceField)

Inter-field relationships should only be checked in derived Config classes after calling this method, and base validation is complete
