Detailed Description

Load an "instcal" exposure as a post-ISR CCD exposure.

Load "instcal" exposures from the community pipeline as a post-ISR exposure,
and optionally persist it as a `postISRCCD`.

This is used to retarget the `isr` subtask in `ProcessCcdTask` when you prefer to use
the community pipeline instead of the LSST software stack to perform ISR on DECam images.

runDataRef()

def lsst.obs.decam.decamNullIsr.DecamNullIsrTask.runDataRef	(		self,
			sensorRef
	)

Load a DECam community pipeline "instcal" exposure as a post-ISR CCD exposure

Parameters
----------
sensorRef : `lsst.daf.persistence.butlerSubset.ButlerDataRef`
    Butler data reference for post-ISR exposure.

Returns
-------
result : `struct`
    A pipeBase.Struct with fields:

    - ``exposure`` : Exposure after application of ISR: the "instcal" exposure, unchanged.
