The main method is `runDataRef`, which takes a single butler data reference for the raw input data. @section pipe_tasks_processCcd_Config Configuration parameters See @ref ProcessCcdConfig @section pipe_tasks_processCcd_Debug Debug variables ProcessCcdTask has no debug output, but its subtasks do. @section pipe_tasks_processCcd_Example A complete example of using ProcessCcdTask The following commands will process all raw data in obs_test's data repository. Note: be sure to specify an `--output` that does not already exist: setup obs_test setup pipe_tasks processCcd.py $OBS_TEST_DIR/data/input --output processCcdOut --id The data is read from the small repository in the `obs_test` package and written `./processCcdOut` (or whatever output you specified). Specifying `--id` with no values processes all data. Add the option `--help` to see more options.

[in] | butler | The butler is passed to the refObjLoader constructor in case it is needed. Ignored if the refObjLoader argument provides a loader directly. |
[in] | psfRefObjLoader | An instance of LoadReferenceObjectsTasks that supplies an external reference catalog for image characterization. May be None if the desired loader can be constructed from the butler argument or all steps requiring a catalog are disabled. |
[in] | astromRefObjLoader | An instance of LoadReferenceObjectsTasks that supplies an external reference catalog for astrometric calibration. May be None if the desired loader can be constructed from the butler argument or all steps requiring a reference catalog are disabled. |

Process one CCD The sequence of operations is: - remove instrument signature - characterize image to estimate PSF and background - calibrate astrometry and photometry @param sensorRef: butler data reference for raw data @return pipe_base Struct containing these fields: - charRes: object returned by image characterization task; an lsst.pipe.base.Struct that will include "background" and "sourceCat" fields - calibRes: object returned by calibration task: an lsst.pipe.base.Struct that will include "background" and "sourceCat" fields - exposure: final exposure (an lsst.afw.image.ExposureF) - background: final background model (an lsst.afw.math.BackgroundList)
