Create a random TransmissionCurve with nontrivial spatial and wavelength variation. Parameters ---------- rng : numpy.random.RandomState Random number generator. minWavelength : float Average minimum wavelength for generated TransmissionCurves (will be randomly perturbed). maxWavelength : float Average maximum wavelength for generated TransmissionCurves (will be randomly perturbed). nWavelengths : int Number of samples in the wavelength dimension. maxRadius : float Average maximum radius for spatial variation (will be perturbed). nRadii : int Number of samples in the radial dimension. perturb: float Fraction by which wavelength and radius bounds should be randomly perturbed.

Make an exposure with stars (modelled as Gaussians) @param bbox: parent bbox of exposure @param kwid: kernel width (and height; kernel is square) @param sky: amount of sky background (counts) @param coordList: a list of [x, y, counts, sigma], where: * x,y are relative to exposure origin * counts is the integrated counts for the star * sigma is the Gaussian sigma in pixels @param addPoissonNoise: add Poisson noise to the exposure?
