ConfigClass = EvaluateLocalWcsPluginConfig | |
Evaluate the local, linear approximation of the Wcs. The aim is to store the local calib value within the catalog for later use in the Science Data Model functors.

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

def lsst.meas.base.plugins.EvaluateLocalWcsPlugin.makeLocalTransformMatrix | ( | self, | |
wcs, | |||
center | |||
) |
Create a local, linear approximation of the wcs transformation matrix. The approximation is created as if the center is at RA=0, DEC=0. All comparing x,y coordinate are relative to the position of center. Matrix is initially calculated with units arcseconds and then converted to radians. This yields higher precision results due to quirks in AST. Parameters ---------- wcs : `lsst.afw.geom.SkyWcs` Wcs to approximate center : `lsst.geom.Point2D` Point at which to evaluate the LocalWcs. Returns ------- localMatrix : `numpy.ndarray` Matrix representation the local wcs approximation with units radians.

def lsst.meas.base.plugins.EvaluateLocalWcsPlugin.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.
