templateFluxScaling	Template flux scaling factor (Fr in ZOGY paper) (float, default 1.0)

Attributes Documentation

doFilterPsfs

Filter PSFs for image-space ZOGY. Aids in reducing artifacts. Subject of future research. (bool, default True)

doTrimKernels

Trim kernels for image-space ZOGY. Speeds up convolutions and shrinks artifacts. Subject of future research. (bool, default False)

ignoreMaskPlanes

Mask planes to ignore for statistics (List, default ('INTRP', 'EDGE', 'DETECTED', 'SAT', 'CR', 'BAD', 'NO_DATA', 'DETECTED_NEGATIVE'))

inImageSpace

Perform all convolutions in real (image) space rather than Fourier space. Currently if True, this results in artifacts when using real (noisy) PSFs. (bool, default False)

padSize

Number of pixels to pad PSFs to avoid artifacts (when inImageSpace is True) (int, default 7)

scienceFluxScaling

Science flux scaling factor (Fn in ZOGY paper) (float, default 1.0)

templateFluxScaling

Template flux scaling factor (Fr in ZOGY paper) (float, default 1.0)
