lsst.obs.base

The lsst.obs.base module provides the framework and common API for telescope/camera specific “obs” packages. New cameras will derive from the classes defined here. lsst.obs.base.tests provides the tests that all “obs” packages should pass.

lsst.obs.base is developed at https://github.com/lsst/obs_base. You can find Jira issues for this module under the obs_base component.

Functions

addUnboundedCalibrationLabel(registry, …)	Add a special ‘unbounded’ calibration_label dimension entry for the given camera that is valid for any exposure.
bboxFromIraf(irafBBoxStr)	Return a Box2I corresponding to an IRAF-style BBOX
createInitialSkyWcs(visitInfo, detector[, flipX])	Create a SkyWcs from the telescope boresight and detector geometry.
exposureFromImage(image[, dataId, mapper, …])	Generate an Exposure from an image-like object
makeExposureRecordFromObsInfo(obsInfo, universe)	Construct an exposure DimensionRecord from astro_metadata_translator.ObservationInfo.
makeTransferChoiceField([doc, default])	Create a Config field with options for how to transfer files between data repositories.
makeVisitRecordFromObsInfo(obsInfo, universe, *)	Construct a visit DimensionRecord from astro_metadata_translator.ObservationInfo.

Classes

CalibrationMapping(datasetType, policy, …)	CalibrationMapping is a Mapping subclass for calibration-type products.
CameraMapper(policy, repositoryDir[, root, …])	CameraMapper is a base class for mappers that handle images from a camera and products derived from them.
DatasetMapping(datasetType, policy, …)	DatasetMapping is a Mapping subclass for non-Exposure datasets that can be retrieved by the standard daf_persistence mechanism.
ExposureIdInfo([expId, expBits, maxBits])	Exposure ID and number of bits used.
ExposureMapping(datasetType, policy, …)	ExposureMapping is a Mapping subclass for normal exposures.
FilterDefinition(physical_filter, lambdaEff)	The definition of an instrument’s filter bandpass.
FilterDefinitionCollection(*filters)	An order-preserving collection of `FilterDefinition`s.
FitsRawFormatterBase(*args, **kwargs)	Abstract base class for reading and writing raw data to and from FITS files.
ImageMapping(datasetType, policy, registry, …)	ImageMapping is a Mapping subclass for non-camera images.
InitialSkyWcsError	For handling failures when creating a SkyWcs from a camera geometry and boresight.
Instrument(*args, **kwargs)	Base class for instrument-specific logic for the Gen3 Butler.
MakeRawVisitInfo([log])	Base class functor to make a VisitInfo from the FITS header of a raw image.
MakeRawVisitInfoViaObsInfo([log])	Base class functor to make a VisitInfo from the FITS header of a raw image using ObservationInfo translators.
Mapping(datasetType, policy, registry, …)	Mapping is a base class for all mappings.
RawIngestConfig
RawIngestTask([config])	Driver Task for ingesting raw data into Gen3 Butler repositories.
