Detailed Description

Load reference objects from astrometry.net index files.

Description

Load reference objects from astrometry.net index files.

Task initialisation

Create a LoadAstrometryNetObjectsTask.

Parameters

[in]	config	configuration (an instance of self.ConfigClass); if None use self.ConfigClass()
[in]	andConfig	astrometry.net data config (an instance of AstromNetDataConfig, or None); if None then use andConfig.py in the astrometry_net_data product (which must be setup)
[in]	kwargs	additional keyword arguments for pipe_base Task.__init__

Exceptions

RuntimeError if andConfig is None and the configuration cannot be found, either because astrometry_net_data is not setup in eups or because the setup version does not include the file "andConfig.py"

Invoking the Task

Configuration parameters

See LoadAstrometryNetObjectsConfig

A complete example of using

LoadAstrometryNetObjectsTask

LoadAstrometryNetObjectsTask is a subtask of AstrometryTask, which is called by PhotoCalTask. See pipe_tasks_photocal_Example.

Constructor & Destructor Documentation

◆ init()

def lsst.meas.extensions.astrometryNet.loadAstrometryNetObjects.LoadAstrometryNetObjectsTask.__init__	(	self,
		config = `None`,
		andConfig = `None`,
		kwargs
	)

Create a LoadAstrometryNetObjectsTask.

Parameters

[in]	config	configuration (an instance of self.ConfigClass); if None use self.ConfigClass()
[in]	andConfig	astrometry.net data config (an instance of AstromNetDataConfig, or None); if None then use andConfig.py in the astrometry_net_data product (which must be setup)
[in]	kwargs	additional keyword arguments for pipe_base Task.__init__

Exceptions

RuntimeError if andConfig is None and the configuration cannot be found, either because astrometry_net_data is not setup in eups or because the setup version does not include the file "andConfig.py"

Member Function Documentation

◆ loadSkyCircle()

def lsst.meas.extensions.astrometryNet.loadAstrometryNetObjects.LoadAstrometryNetObjectsTask.loadSkyCircle	(	self,
		ctrCoord,
		radius,
		filterName = `None`
	)

Load reference objects that overlap a circular sky region.

Parameters

[in]	ctrCoord	center of search region (an afwGeom.Coord)
[in]	radius	radius of search region (an afwGeom.Angle)
[in]	filterName	name of filter, or None for the default filter; used for flux values in case we have flux limits (which are not yet implemented)

Returns

an lsst.pipe.base.Struct containing:

refCat a catalog of reference objects with the standard schema as documented in LoadReferenceObjects, including photometric, resolved and variable; hasCentroid is False for all objects.
fluxField = name of flux field for specified filterName
