Attributes Documentation

amp_boundary#: Amplifier boundary to ignore when computing gradients/gain ratios (pixels). (int, default 20)

bin_factor#: Binning factor to compute gradients/gain ratios (pixels). (int, default 8)

chebyshev_gradient_order#: Order of chebyshev x/y polynomials to remove additional gradients. (int, default 1)

connections: pexConfig.ConfigField#: Field which refers to a dynamically added configuration class which is based on a PipelineTaskConnections class.

do_remove_radial_gradient#: Remove radial gradient before fitting amp gain ratios? (bool, default True)

max_adu#: Maximum number of adu for an exposure to use in gain ratio calculation. (float, default 20000.0)
