Calibration containing deferred charge/CTI parameters. Parameters ---------- **kwargs : Additional parameters to pass to parent constructor. Notes ----- The charge transfer inefficiency attributes stored are: driftScale : `dict` [`str`, `float`] A dictionary, keyed by amplifier name, of the local electronic offset drift scale parameter, A_L in Snyder+2021. decayTime : `dict` [`str`, `float`] A dictionary, keyed by amplifier name, of the local electronic offset decay time, \tau_L in Snyder+2021. globalCti : `dict` [`str`, `float`] A dictionary, keyed by amplifier name, of the mean global CTI paramter, b in Snyder+2021. serialTraps : `dict` [`str`, `lsst.ip.isr.SerialTrap`] A dictionary, keyed by amplifier name, containing a single serial trap for each amplifier.

lsst.ip.isr.deferredCharge.DeferredChargeCalib.fromDetector | ( | self, | |
detector ) |
Read metadata parameters from a detector. Parameters ---------- detector : `lsst.afw.cameraGeom.detector` Input detector with parameters to use. Returns ------- calib : `lsst.ip.isr.Linearizer` The calibration constructed from the detector.

lsst.ip.isr.deferredCharge.DeferredChargeCalib.fromDict | ( | cls, | |
dictionary ) |
Construct a calibration from a dictionary of properties. Parameters ---------- dictionary : `dict` Dictionary of properties. Returns ------- calib : `lsst.ip.isr.CalibType` Constructed calibration. Raises ------ RuntimeError Raised if the supplied dictionary is for a different calibration.

lsst.ip.isr.deferredCharge.DeferredChargeCalib.fromTable | ( | cls, | |
tableList ) |
Construct calibration from a list of tables. This method uses the ``fromDict`` method to create the calibration, after constructing an appropriate dictionary from the input tables. Parameters ---------- tableList : `list` [`lsst.afw.table.Table`] List of tables to use to construct the crosstalk calibration. Two tables are expected in this list, the first containing the per-amplifier CTI parameters, and the second containing the parameters for serial traps. Returns ------- calib : `lsst.ip.isr.DeferredChargeCalib` The calibration defined in the tables. Raises ------ ValueError Raised if the trap type or trap coefficients are not defined properly.

lsst.ip.isr.deferredCharge.DeferredChargeCalib.toDict | ( | self | ) |
Return a dictionary containing the calibration properties. The dictionary should be able to be round-tripped through ``fromDict``. Returns ------- dictionary : `dict` Dictionary of properties.

lsst.ip.isr.deferredCharge.DeferredChargeCalib.toTable | ( | self | ) |
Construct a list of tables containing the information in this calibration. The list of tables should create an identical calibration after being passed to this class's fromTable method. Returns ------- tableList : `list` [`lsst.afw.table.Table`] List of tables containing the crosstalk calibration information. Two tables are generated for this list, the first containing the per-amplifier CTI parameters, and the second containing the parameters for serial traps.
