@anchor ProcessCcdTask_ @section pipe_tasks_processCcd_Contents Contents - @ref pipe_tasks_processCcd_Purpose - @ref pipe_tasks_processCcd_Initialize - @ref pipe_tasks_processCcd_IO - @ref pipe_tasks_processCcd_Config - @ref pipe_tasks_processCcd_Debug - @ref pipe_tasks_processCcd_Example @section pipe_tasks_processCcd_Purpose Description Perform the following operations: - Call isr to unpersist raw data and assemble it into a post-ISR exposure - Call charImage subtract background, fit a PSF model, repair cosmic rays, detect and measure bright sources, and measure aperture correction - Call calibrate to perform deep detection, deblending and single-frame measurement, refine the WCS and fit the photometric zero-point @section pipe_tasks_processCcd_Initialize Task initialisation @copydoc \_\_init\_\_ @section pipe_tasks_processCcd_IO Invoking the Task This task is primarily designed to be run from the command line. 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.

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)
