Abstract base class for a generic plugin A generic plugin can be used with the `singleFramePluginFromGeneric` and/or `forcedPluginFromGeneric` wrappers to create classes that can be used for single frame measurement and/or forced measurement (as appropriate). The only real difference between `SingleFramePlugin` and `ForcedPlugin` is the `measure` method; this class introduces a shared signature for the `measure` method that, in combination with the afore-mentioned wrappers, allows both plugin styles to share a single implementation. This doesn't use abc.ABCMeta because I couldn't get it to work with a superclass. Sub-classes should set `ConfigClass` and implement the `measure` and `measureN` methods. They may optionally provide alternative implementations for the `__init__`, `fail` and `getExecutionOrder` methods. Constructor parameters ---------------------- config : `lsst.pex.config.Config` An instance of this class' ConfigClass. name : `str` Name of this measurement plguin, for registering. schema : `lsst.afw.table.Schema` The catalog schema. New fields should be added here to hold measurements produced by this plugin. metadata : `lsst.daf.base.PropertySet` Metadata that will be attached to the output catalog. logName : `str` Name of log component.

def lsst.meas.base.wrappers.GenericPlugin.fail | ( | self, | |
measRecord, | |||
error = None |

Record failure This default implementation simply records the failure in the source record. Parameters ---------- measRecord : `lsst.afw.table.SourceRecord` Catalog record for the source being measured. error : `Exception` Error causing failure, or `None`.

Get the measurement transformation appropriate to this plugin.
This returns a subclass of MeasurementTransform, which may be instantiated with details of the algorithm configuration and then called with information about calibration and WCS to convert from raw measurement quantities to calibrated units. Calibrated data is then provided in a separate output table.
By default, we copy everything from the input to the output without transformation.

def lsst.meas.base.wrappers.GenericPlugin.makeForcedPlugin | ( | cls, | |
name | |||
) |
Produce a ForcedPlugin sub-class from this GenericPlugin class The class is also registered. Parameters ---------- name : `str` Name of plugin to register.
Definition at line 600 of file wrappers.py.
def lsst.meas.base.wrappers.GenericPlugin.makeSingleFramePlugin | ( | cls, | |
name | |||
) |
Produce a SingleFramePlugin sub-class from this GenericPlugin class The class is also registered. Parameters ---------- name : `str` Name of plugin to register.

def lsst.meas.base.wrappers.GenericPlugin.measure | ( | self, | |
measRecord, | |||
exposure, | |||
center | |||
) |
Measure source It is the responsibility of this method to perform the desired measurement and record the result in the `measRecord`. Parameters ---------- measRecord : `lsst.afw.table.SourceRecord` Catalog record for the source being measured. exposure : `lsst.afw.image.Exposure` Exposure on which the source is being measured. center : `lsst.geom.Point2D` Pixel coordinates of the object. Raises ------ `MeasurementError` If the measurement fails for a known/justifiable reason.

def lsst.meas.base.wrappers.GenericPlugin.measureN | ( | self, | |
measCat, | |||
exposure, | |||
refCat, | |||
refWcs | |||
) |
Measure multiple sources It is the responsibility of this method to perform the desired measurement and record the result in the `measCat`. Parameters ---------- measCat : `lsst.afw.table.SourceCatalog` Catalog for the sources being measured. exposure : `lsst.afw.image.Exposure` Exposure on which the source is being measured. refCat : `lsst.afw.table.SourceCatalog` Reference catalog. refWcs : `lsst.afw.image.Wcs` Astrometric solution for the reference image. Raises ------ `MeasurementError` If the measurement fails for a known/justifiable reason.
