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 : `lsst.log.Log`, optional
    Log for messages.

Constructor & Destructor Documentation

◆ __init__()

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

Reimplemented in lsst.ip.isr.ptcDataset.PhotonTransferCurveDataset.

Definition at line 65 of file calibType.py.

Member Function Documentation

◆ __eq__()

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

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

Reimplemented in lsst.ip.isr.defects.Defects, and lsst.ip.isr.calibType.IsrProvenance.

Definition at line 93 of file calibType.py.

◆ __str__()

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

Reimplemented in lsst.ip.isr.defects.Defects, and lsst.ip.isr.calibType.IsrProvenance.

Definition at line 90 of file calibType.py.

◆ apply()

def 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`

expect to find everything in the metadata, they still need to
search through dictionaries.

    Source for the common keywords.

Raises
------
RuntimeError :
    Raised if the dictionary does not match the expected OBSTYPE.

NotImplementedError
    This needs to be implemented by subclasses for each
    calibration type.
