ConfigClass = SingleFrameJacobianConfig | |
Compute the Jacobian and its ratio with a nominal pixel area. This enables one to compare relative, rather than absolute, pixel areas. Parameters ---------- config : `SingleFrameJacobianConfig` 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

lsst.meas.base.plugins.SingleFrameJacobianPlugin.fail | ( | self, | |
measRecord, | |||
error = None ) |
Record a failure of the `measure` or `measureN` method. Parameters ---------- measRecord : `lsst.afw.table.SourceRecord` Table record describing the source being measured. error : `MeasurementError`, optional Only provided if the measurement failed due to a `MeasurementError` being raised; otherwise, will be `None`. Notes ----- When the plugin raises an exception, framework will call `BasePlugin.fail` to allow the plugin to set its failure flag field(s). When `BasePlugin.measureN` raises an exception, `BasePlugin.fail` will be called repeatedly with all the records that were being measured. If the exception is an `MeasurementError`, it will be passed as the error argument; in all other cases the error argument will be `None`, and the failure will be logged by the measurement framework as a warning.

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

lsst.meas.base.plugins.SingleFrameJacobianPlugin.measure | ( | self, | |
measRecord, | |||
exposure ) |
Measure the properties of a source on a single image. The image may be from a single epoch, or it may be a coadd. Parameters ---------- measRecord : `lsst.afw.table.SourceRecord` Record describing the object being measured. Previously-measured quantities may be retrieved from here, and it will be updated in-place tih the outputs of this plugin. exposure : `lsst.afw.image.ExposureF` The pixel data to be measured, together with the associated PSF, WCS, etc. All other sources in the image should have been replaced by noise according to deblender outputs.
