asf

jwst.ami.analyticnrm2.asf(detpixel, fov, oversample, d, lam, psf_offset)

Calculate the Amplitude Spread Function for a circular aperture.

Amplitude Spread Function is also know as image plane complex amplitude.

Parameters:

detpixelfloat

Pixel scale

fovint

Number of detector pixels on a side

oversampleint

Oversampling factor

dfloat

Hole diameter

lamfloat

Wavelength

psf_offset2D float array

Offset from image center in detector pixels

Returns:

asf2D real array

Amplitude Spread Function (a.k.a. image plane complex amplitude) for a circular aperture
