Detailed Description

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.

Constructor & Destructor Documentation

◆ init()

lsst.ip.isr.calibType.IsrCalib.__init__	(		self,
			camera = None,
			detector = None,
			log = None,
		**	kwargs )

Definition at line 68 of file calibType.py.

Member Function Documentation

◆ eq()

lsst.ip.isr.calibType.IsrCalib.__eq__	(		self,
			other )

Calibration equivalence.

Running ``calib.log.setLevel(0)`` enables debug statements to
identify problematic fields.

Definition at line 105 of file calibType.py.

◆ str()

lsst.ip.isr.calibType.IsrCalib.__str__ ( self )

Definition at line 102 of file calibType.py.

◆ apply()

lsst.ip.isr.calibType.IsrCalib.apply	(		self,
			target )

Method to apply the calibration to the target object.

Parameters
----------
target : `object`
    Thing to validate against.

Returns
-------
valid : `bool`
    Returns true if the calibration was applied correctly.

Raises
------
NotImplementedError

Definition at line 706 of file calibType.py.

◆ calibInfoFromDict()

lsst.ip.isr.calibType.IsrCalib.calibInfoFromDict	(		self,

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 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).
