additionalCuratedDatasetTypes = frozenset()¶

configPaths¶

Built-in immutable sequence.

If no argument is given, the constructor returns an empty tuple. If iterable is specified the tuple is initialized from iterable’s items.

If the argument is a tuple, the return value is the same object.

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

instrument = 'LSST-UCDCam'¶

obsDataPackage = 'obs_lsst_data'¶

policyName = 'ucd'¶

standardCuratedDatasetTypes = frozenset({'defects', 'crosstalk', 'qe_curve'})¶

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.

extractDetectorRecord(camGeomDetector)¶: Create a Gen3 Detector entry dict from a cameraGeom.Detector.

static fromName(name: str, registry: Registry) → Instrument¶

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

Parameters:	name : `str` Name of the instrument (must match the return value of `getName`). 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.

classmethod 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.

classmethod getCuratedCalibrationNames() → Set[str]¶

Return the names of all the curated calibration dataset types.

Returns:	names : `set` of `str` The dataset type names of all curated calibrations. This will include the standard curated calibrations even if the particular instrument does not support them.

Notes

The returned list does not indicate whether a particular dataset is present in the Butler repository, simply that these are the dataset types that are handled by writeCuratedCalibrations.

classmethod getName()¶

Return the short (dimension) name for this instrument.

This is not (in general) the same as the class name - it’s what is used as the value of the “instrument” field in data IDs, and is usually an abbreviation of the full name.

classmethod getObsDataPackageDir()¶

The root of the obs data package that provides specializations for this instrument.

Returns:	dir : `str` The root of the relevat obs data package.

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.

static importAll(registry: Registry) → None¶

Import all the instruments known to this registry.

This will ensure that all metadata translators have been registered.

Parameters:	registry : `lsst.daf.butler.Registry` Butler registry to query to find the information.

Notes

It is allowed for a particular instrument class to fail on import. This might simply indicate that a particular obs package has not been setup.

classmethod makeCollectionName(label: str) → str¶

Get the instrument-specific collection string to use as derived from the supplied label.

Parameters:	label : `str` String to be combined with the instrument name to form a collection name.
Returns:	name : `str` Collection name to use that includes the instrument name.

makeDataIdTranslatorFactory() → lsst.obs.base.gen2to3.translators.TranslatorFactory¶

Return a factory for creating Gen2->Gen3 data ID translators, specialized for this instrument.

Derived class implementations should generally call TranslatorFactory.addGenericInstrumentRules with appropriate arguments, but are not required to (and may not be able to if their Gen2 raw data IDs are sufficiently different from the HSC/DECam/CFHT norm).

Returns:	factory : `TranslatorFactory`. Factory for `Translator` objects.

classmethod makeDefaultRawIngestRunName() → str¶

Make the default instrument-specific run collection string for raw data ingest.

Returns:	coll : `str` Run collection name to be used as the default for ingestion of raws.

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

writeAdditionalCuratedCalibrations(butler, run=None)¶

Write additional curated calibrations that might be instrument specific and are not part of the standard set.

Default implementation does nothing.

Parameters:	butler : `lsst.daf.butler.Butler` Butler to use to store these calibrations. run : `str`, optional Name of the run to use to override the default run associated with this Butler.

writeCameraGeom(butler, run=None)¶

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. run : `str`, optional Name of the run to use to override the default run associated with this Butler.

writeCuratedCalibrations(butler, run=None)¶

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. run : `str` Run to use for this collection of calibrations. If `None` the collection name is worked out automatically from the instrument name and other metadata.

Notes

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

writeStandardTextCuratedCalibrations(butler, run=None)¶

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

Parameters:	butler : `lsst.daf.butler.Butler` Butler to receive these calibration datasets. run : `str`, optional Name of the run to use to override the default run associated with this Butler.
