ConfigClass = ScaleZeroPointConfig | |
Compute scale factor to scale exposures to a desired photometric zero point This simple version assumes that the zero point is spatially invariant.

Construct a ScaleZeroPointTask

def lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.computeImageScaler | ( | self, | |
exposure, | |||
dataRef = None |
|||
) |
Compute image scaling object for a given exposure. @param[in] exposure: exposure for which scaling is desired @param[in] dataRef: dataRef for exposure. Not used, but in API so that users can switch between spatially variant and invariant tasks
Reimplemented in lsst.pipe.tasks.scaleZeroPoint.SpatialScaleZeroPointTask.

def lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.getPhotoCalib | ( | self | ) |
Get desired PhotoCalib @return calibration (lsst.afw.image.PhotoCalib) with fluxMag0 set appropriately for config.zeroPoint

def lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.run | ( | self, | |
exposure, | |||
dataRef = None |
|||
) |
Scale the specified exposure to the desired photometric zeropoint @param[in,out] exposure: exposure to scale; masked image is scaled in place @param[in] dataRef: dataRef for exposure. Not used, but in API so that users can switch between spatially variant and invariant tasks @return a pipeBase.Struct containing: - imageScaler: the image scaling object used to scale exposure

def lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.scaleFromFluxMag0 | ( | self, | |
fluxMag0 | |||
) |
Compute the scale for the specified fluxMag0 This is a wrapper around scaleFromPhotoCalib, which see for more information @param[in] fluxMag0 @return a pipeBase.Struct containing: - scale, as described in scaleFromPhotoCalib.
Definition at line 202 of file scaleZeroPoint.py.
def lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.scaleFromPhotoCalib | ( | self, | |
calib | |||
) |
Compute the scale for the specified PhotoCalib Compute scale, such that if pixelCalib describes the photometric zeropoint of a pixel then the following scales that pixel to the photometric zeropoint specified by config.zeroPoint: scale = computeScale(pixelCalib) pixel *= scale @return a pipeBase.Struct containing: - scale, as described above. @note: returns a struct to leave room for scaleErr in a future implementation.
