filterDefinitions = <lsst.obs.base.filters.FilterDefinitionCollection object>¶

Methods Documentation

applyConfigOverrides(name, config)¶

Apply instrument-specific overrides for a task config.

Parameters:	name : `str` Name of the object being configured; typically the _DefaultName of a Task. config : `lsst.pex.config.Config` Config instance to which overrides should be applied.

classmethod fromName(name, registry)¶

Given an instrument name and a butler, retrieve a corresponding instantiated instrument object.

Parameters:	name : `str` Name of the instrument (must match the name property of an instrument class). registry : `lsst.daf.butler.Registry` Butler registry to query to find the information.
Returns:	instrument : `Instrument` An instance of the relevant `Instrument`.
Raises:	LookupError Raised if the instrument is not known to the supplied registry. ModuleNotFoundError Raised if the class could not be imported. This could mean that the relevant obs package has not been setup. TypeError Raised if the class name retrieved is not a string.

Notes

The instrument must be registered in the corresponding butler.

getCamera()¶

Retrieve the cameraGeom representation of this instrument.

This is a temporary API that should go away once obs_ packages have a standardized approach to writing versioned cameras to a Gen3 repo.

getRawFormatter(dataId)¶

Return the Formatter class that should be used to read a particular raw file.

Parameters:	dataId : `DataCoordinate` Dimension-based ID for the raw file or files being ingested.
Returns:	formatter : `Formatter` class Class to be used that reads the file into an `lsst.afw.image.Exposure` instance.

register(registry)¶: Insert instrument, physical_filter, and detector entries into a Registry.

writeCameraGeom(butler)¶

Write the default camera geometry to the butler repository with an infinite validity range.

Parameters:	butler : `lsst.daf.butler.Butler` Butler to receive these calibration datasets.

writeCuratedCalibrations(butler)¶

Write human-curated calibration Datasets to the given Butler with the appropriate validity ranges.

Parameters:	butler : `lsst.daf.butler.Butler` Butler to use to store these calibrations.

Notes

Expected to be called from subclasses. The base method calls writeCameraGeom and writeStandardTextCuratedCalibrations.

writeStandardTextCuratedCalibrations(butler)¶

Write the set of standardized curated text calibrations to the repository.

Parameters:	butler : `lsst.daf.butler.Butler` Butler to receive these calibration datasets.
