Image difference Task used in the Winter 2013 data challege.
Enables testing the effects of registration shifts and scatter.
For use with winter 2013 simulated images: Use –templateId visit=88868666 for sparse data –templateId visit=22222200 for dense data (g) –templateId visit=11111100 for dense data (i)

Subtract an image from a template coadd and measure the result Steps include: - warp template coadd to match WCS of image - PSF match image to warped template - subtract image from PSF-matched, warped template - persist difference image - detect sources - measure sources @param sensorRef: sensor-level butler data reference, used for the following data products: Input only: - calexp - psf - ccdExposureId - ccdExposureId_bits - self.config.coaddName + "Coadd_skyMap" - self.config.coaddName + "Coadd" Input or output, depending on config: - self.config.coaddName + "Diff_subtractedExp" Output, depending on config: - self.config.coaddName + "Diff_matchedExp" - self.config.coaddName + "Diff_src" @return pipe_base Struct containing these fields: - subtractedExposure: exposure after subtracting template; the unpersisted version if subtraction not run but detection run None if neither subtraction nor detection run (i.e. nothing useful done) - subtractRes: results of subtraction task; None if subtraction not run - sources: detected and possibly measured sources; None if detection not run
