DipoleFitTask

class lsst.ip.diffim.DipoleFitTask(schema, algMetadata=None, **kwds)

Bases: lsst.meas.base.sfm.SingleFrameMeasurementTask

!Subclass of SingleFrameMeasurementTask which accepts up to three input images in its run() method.

Because it subclasses SingleFrameMeasurementTask, and calls SingleFrameMeasurementTask.run() from its run() method, it still can be used identically to a standard SingleFrameMeasurementTask.

Methods Summary

run(sources, exposure[, posExp, negExp])

!Run dipole measurement and classification

Methods Documentation

run(sources, exposure, posExp=None, negExp=None, **kwds)

!Run dipole measurement and classification

@param sources diaSources that will be measured using dipole measurement @param exposure Difference exposure on which the diaSources were detected; exposure = posExp - negExp @param posExp “Positive” exposure, typically a science exposure, or None if unavailable @param negExp “Negative” exposure, typically a template exposure, or None if unavailable @param **kwds Sent to SingleFrameMeasurementTask

@note When posExp is None, will compute posImage = exposure + negExp. Likewise, when negExp is None, will compute negImage = posExp - exposure. If both posExp and negExp are None, will attempt to fit the dipole to just the exposure with no constraint.
