Abstract base class for a generic plugin. 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`, optional Name of log component. Notes ----- 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 `measure` that, in combination with the aforementioned 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. This default implementation simply adds a field for recording a fatal failure of the measurement plugin.

def lsst.meas.base.wrappers.GenericPlugin.fail | ( | self, | |

Record a measurement 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`.

def lsst.meas.base.wrappers.GenericPlugin.getExecutionOrder | ( | cls | ) |
Get the relative execution order of this plugin. Must be reimplemented as a class method by concrete derived classes.

Get the measurement transformation appropriate to this plugin. This returns a subclass of `transforms.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. Notes ----- 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 subclass from this GenericPlugin class. The class is also registered. Parameters ---------- name : `str` Name of plugin to register.
Definition at line 623 of file wrappers.py.
def lsst.meas.base.wrappers.GenericPlugin.makeSingleFramePlugin | ( | cls, | |
name | |||

Produce a SingleFramePlugin subclass 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 a single 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 Raised if the measurement fails for a known/justifiable reason.

def lsst.meas.base.wrappers.GenericPlugin.measureN | ( | self, | |
measCat, | |||
exposure, | |||
refCat, | |||

) |
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 Raised if the measurement fails for a known/justifiable reason.
