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 meas_photocal_photocal_Example.

Debug variables

LoadAstrometryNetObjectsTask does not support any debug variables.

Parameters

[in]	config	configuration (an instance of self.ConfigClass); if None use self.ConfigClass()
