rawCallback
(im, ccd=None, imageSource=None, correctGain=False, subtractBias=False, convertToFloat=False)¶ A callback function that may or may not subtract bias/correct gain/trim a raw image.
Parameters: - im :
lsst.afw.image.Image
orlsst.afw.image.MaskedImage
orlsst.afw.image.Exposure
An image of a chip, ready to be binned and maybe rotated.
- ccd :
lsst.afw.cameraGeom.Detector
or None The Detector; if None assume that im is an exposure and extract its Detector.
- imageSource :
FakeImageDataSource
or None Source to get ccd images. Must have a
getCcdImage()
method.- correctGain :
bool
Correct each amplifier for its gain?
- subtractBias :
bool
Subtract the bias from each amplifier?
- convertToFloat :
bool
Convert im to floating point if possible.
Returns: - image :
lsst.afw.image.Image
like The constructed image (type returned by
im.Factory
).
Notes
If imageSource is derived from ButlerImage, imageSource.butler is available.
