Generic calibration type. Subclasses must implement the toDict, fromDict, toTable, fromTable methods that allow the calibration information to be converted from dictionaries and afw tables. This will allow the calibration to be persisted using the base class read/write methods. The validate method is intended to provide a common way to check that the calibration is valid (internally consistent) and appropriate (usable with the intended data). The apply method is intended to allow the calibration to be applied in a consistent manner. Parameters ---------- camera : `lsst.afw.cameraGeom.Camera`, optional Camera to extract metadata from. detector : `lsst.afw.cameraGeom.Detector`, optional Detector to extract metadata from. log : `logging.Logger`, optional Log for messages.

def lsst.ip.isr.calibType.IsrCalib.apply | ( | self, | |

def lsst.ip.isr.calibType.IsrCalib.calibInfoFromDict | ( | self, | |
dictionary | |||
) |
Handle common keywords. This isn't an ideal solution, but until all calibrations expect to find everything in the metadata, they still need to search through dictionaries. Parameters ---------- dictionary : `dict` or `lsst.daf.base.PropertyList` Source for the common keywords. Raises ------ RuntimeError : Raised if the dictionary does not match the expected OBSTYPE.

metadata, | |||
message | |||
) |
Attempt to find calibration class in metadata. Parameters ---------- metadata : `dict` or `lsst.daf.base.PropertyList` Metadata possibly containing a calibration class entry. message : `str` Message to include in any errors. Returns ------- calibClass : `object` The class to use to read the file contents. Should be an `lsst.ip.isr.IsrCalib` subclass. Raises ------ ValueError : Raised if the resulting calibClass is the base `lsst.ip.isr.IsrClass` (which does not implement the content methods).

** | kwargs | ||
) |
Read calibration data from a FITS file. Parameters ---------- filename : `str` Filename to read data from. kwargs : `dict` or collections.abc.Mapping`, optional Set of key=value pairs to pass to the ``fromTable`` method. Returns ------- calib : `lsst.ip.isr.IsrCalib` Calibration contained within the file.

Read calibration representation from a yaml/ecsv file. Parameters ---------- filename : `str` Name of the file containing the calibration definition. kwargs : `dict` or collections.abc.Mapping`, optional Set of key=value pairs to pass to the ``fromDict`` or ``fromTable`` methods.
