gaussian_2d_fixedwidth_offset

gaussian_2d_fixedwidth_offset(height, center_x, center_y, offset)

Returns a gaussian function + offset with the given parameters

sigma is unique and fixed.

FWHM_fit = FWHM_PSF = sqrt(m**2+d**2) (=sqrt(m**2+1) en pixel) m = mask element d = detector pitch sigma = sqrt(m**2+1)/2.3548 (with m=2.53) sigma = 1.155 pixel

Parameters:

• height (float) – height of the gaussian function
• center_x (float) – center in x of the gaussian function
• center_y (float) – center in y of the gaussian function
• offset – offset of the gaussian function

:type offset float

Returns:gaussian function with the given parameters Return type:lambda function
