Compute the median variance corresponding to a footprint. The aim here is to measure the background variance, rather than that of the object itself. In order to achieve this, the variance is calculated over an area scaled up from the shape of the input footprint. Parameters ---------- config : `VarianceConfig` Plugin configuraion. name : `str` Plugin name. schema : `lsst.afw.table.Schema` The schema for the measurement output catalog. New fields will be added to hold measurements produced by this plugin. metadata : `lsst.daf.base.PropertySet` Plugin metadata that will be attached to the output catalog

def lsst.meas.base.plugins.VariancePlugin.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.plugins.VariancePlugin.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.
Reimplemented in lsst.meas.base.plugins.ForcedPeakCentroidPlugin, and lsst.meas.base.plugins.SingleFramePeakCentroidPlugin.

def lsst.meas.base.plugins.VariancePlugin.measure | ( | self, | |

) |
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.

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.
