NoiseReplacerConfig

class lsst.meas.base.NoiseReplacerConfig(*args, **kw)

Bases: Config

Noise replacement configuration.

Attributes Summary

noiseOffset	Add ann offset to the generated noise.
noiseSeedMultiplier	The seed multiplier value to use for random number generation: >= 1: set the seed deterministically based on exposureId 0: fall back to the afw.math.Random default constructor (which uses a seed value of 1) (int, default 1)
noiseSource	How to choose mean and variance of the Gaussian noise we generate? (str, default 'measure')

Attributes Documentation

noiseOffset

Add ann offset to the generated noise. (float, default 0.0)

noiseSeedMultiplier

The seed multiplier value to use for random number generation: >= 1: set the seed deterministically based on exposureId 0: fall back to the afw.math.Random default constructor (which uses a seed value of 1) (int, default 1)

noiseSource

How to choose mean and variance of the Gaussian noise we generate? (str, default 'measure')

Allowed values:

'measure'

Measure clipped mean and variance from the whole image

'meta'

Mean = 0, variance = the “BGMEAN” metadata entry

'variance'

Mean = 0, variance = the image’s variance

'variance_median'

Mean = 0, variance = median(variance plane)
