Documentation for existing data processing Tasks

Tasks are scattered over various implementation products and gathered together by their membership of the doxygen group LSST_task_documentation.

AssembleCcdTask Assemble a set of amplifier images into a full detector size set of pixels.

IsrTask Apply common instrument signature correction algorithms to a raw frame.

BaseMeasurementTask Ultimate base class for all measurement tasks.

A subtask for measuring the properties of sources on a single exposure, using an existing

"reference" catalog to constrain some aspects of the measurement.

ForcedPhotCcdTask A command-line driver for performing forced measurement on CCD images.

ForcedPhotCoaddTask A command-line driver for performing forced measurement on coadd images.

ProcessImageForcedTask A base class for command-line forced measurement drivers.

SingleFrameMeasurementTask A subtask for measuring the properties of sources on a single exposure.

ANetAstrometryTask Use astrometry.net to match input sources with a reference catalog and solve for the Wcs

AstrometryTask Match an input source catalog with objects from a reference catalog and solve for the WCS

FitTanSipWcsTask Fit a TAN-SIP WCS given a list of reference object/source matches

LoadAstrometryNetObjectsTask Load reference objects from astrometry.net index files

MatchOptimisticBTask Match sources to reference objects

PhotoCalTask Detect positive and negative sources on an exposure and return a new SourceCatalog.

CalibrateTask Calibrate an exposure: measure PSF, subtract background, measure astrometry and photometry.

ExampleCmdLineTask An example intended to show how to write a command-line task.

ExampleSigmaClippedStatsTask A simple example subtask that computes sigma-clipped statistics of an image
ExampleSimpleStatsTask A very simple example subtask that computes statistics of an image.

MeasurePsfTask Measure the PSF.

RepairTask Interpolate over defects in an exposure and handle cosmic rays.

TransformTask Task for transforming raw measurement outputs to calibrated quantities.

DipoleMeasurementTask Measurement of Sources, specifically ones from difference images, for characterization as dipoles.

ImagePsfMatchTask Psf-match two MaskedImages or Exposures using the sources in the images.

ModelPsfMatchTask Matching of two model Psfs, and application of the Psf-matching kernel to an input Exposure.

PsfMatchTask Base class for Psf Matching; should not be called directly.

SnapPsfMatchTask Image-based Psf-matching of two subsequent snaps from the same visit.

SourceDeblendTask Split blended sources into individual sources.

SourceDetectionTask Detect positive and negative sources on an exposure and return a new table.SourceCatalog.
