Detailed Description

Subtask to retrieve calexp of the same ccd number as the science image SensorRef
for use as an image difference template. Only gen2 supported.

To be run as a subtask by pipe.tasks.ImageDifferenceTask.
Intended for use with simulations and surveys that repeatedly visit the same pointing.
This code was originally part of Winter2013ImageDifferenceTask.

◆ run()

def lsst.ip.diffim.getTemplate.GetCalexpAsTemplateTask.run (   self,
  exposure,
  sensorRef,
  templateIdList 
)
Return a calexp exposure with based on input sensorRef.

Construct a dataId based on the sensorRef.dataId combined
with the specifications from the first dataId in templateIdList

Parameters
----------
exposure :  `lsst.afw.image.Exposure`
    exposure (unused)
sensorRef : `list` of `lsst.daf.persistence.ButlerDataRef`
    Data reference of the calexp(s) to subtract from.
templateIdList : `list` of `lsst.daf.persistence.ButlerDataRef`
    Data reference of the template calexp to be subtraced.
    Can be incomplete, fields are initialized from `sensorRef`.
    If there are multiple items, only the first one is used.

Returns
-------
result : `struct`

    return a pipeBase.Struct:

- ``exposure`` : a template calexp
- ``sources`` : source catalog measured on the template
