harmonicfringes
- jwst.ami.analyticnrm2.harmonicfringes(fov, pitch, baseline, lam, oversample, affine2d, psf_offset=(0, 0))[source]
Calculate the sine and cosine fringes.
This is in image space and, for later versions, this works in the oversampled space that is each slice of the model.
- Parameters:
- fovint, default=None
Number of detector pixels on a side
- pitchfloat
Sampling pitch in radians in image plane
- baseline2D float array
Hole centers vector, units of meters.
- lamfloat
Wavelength in meters.
- oversampleint
Number of samples per detector pixel pitch
- affine2dAffine2d object
The affine2d object
- psf_offset2D float array, optional
Offset from image center in detector pixels, default is (0,0).
- Returns:
- (cosine_fringes, sine_fringes)tuple
Sine and cosine fringes: float arrays
