str | _DefaultName = "scaleZeroPoint" |
Compute scale factor to scale exposures to a desired photometric zero point. This simple version assumes that the zero point is spatially invariant.

lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.computeImageScaler | ( | self, | |
exposure, | |||
dataRef = None ) |
Compute image scaling object for a given exposure. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure for which scaling is desired. dataRef : `Unknown`, optional Data reference 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.
Definition at line 198 of file scaleZeroPoint.py.
lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.getPhotoCalib | ( | self | ) |
Get desired PhotoCalib. Returns ------- calibration : `lsst.afw.image.PhotoCalib` Calibration with ``fluxMag0`` set appropriately for config.zeroPoint.
Definition at line 213 of file scaleZeroPoint.py.
lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.run | ( | self, | |
exposure, | |||
dataRef = None ) |
Scale the specified exposure to the desired photometric zeropoint. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to scale; masked image is scaled in place. dataRef : `Unknown` Data reference for exposure. Not used, but in API so that users can switch between spatially variant and invariant tasks. Returns ------- result : `lsst.pipe.base.Struct` Results as a struct with attributes: ``imageScaler`` The image scaling object used to scale exposure.
Reimplemented in lsst.pipe.tasks.scaleZeroPoint.SpatialScaleZeroPointTask.

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. Parameters ---------- fluxMag0 : `float` Flux at magnitude zero. Returns ------- result : `lsst.pipe.base.Struct` Results as a struct with attributes: `scale` 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``
Definition at line 247 of file scaleZeroPoint.py.
lsst.pipe.tasks.scaleZeroPoint.ScaleZeroPointTask.scaleFromPhotoCalib | ( | self, | |
calib ) |
Compute the scale for the specified PhotoCalib. Returns ------- result : `lsst.pipe.base.Struct` Results as a struct with attributes: `scale` 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`` Notes ----- Returns a struct to leave room for scaleErr in a future implementation.
