PSF Sampling

What the values of a measured PSF are, for CameraModelHandle.set_measured_psf(). See The Point Spread Function.

class huira.PSFSampling

What the values of a measured PSF are, so that they become pixel values correctly.

Members:

PointSampled : The PSF’s brightness at each sample’s position: a PSF from an optical design software, from a model, or measured with pixels much smaller than the simulated sensor’s. Huira interpolates between the samples and adds up the pattern over each pixel. Sample it finely, 4 or more samples per pixel.

PixelIntegrated : What a pixel of the simulated sensor collects with its center at each sample: a star image taken with that sensor (1 sample per pixel), or an effective PSF combined from many such images at subpixel offsets (more). The pixel’s area is already included, so Huira uses the values as they are.

PixelIntegrated = <PSFSampling.PixelIntegrated: 1>

PointSampled = <PSFSampling.PointSampled: 0>
