+	Description:
+	This script generates a point spread function of the MICADO optical model.
+	Here we apply a Bahtinov mask to the pupil and simulate a broadband PSF,
+	done through the summation of multiple (here: 15) wavelength slices. 
+	When there is atmospheric dispersion, the diffraction speckles created by the 
+	Bahtinov mask will start to point to a location outside the zeroth order 
+	PSF core.
+	Here, atmospheric dispersion is modelled as a wavelength dependent phase
+	tilt.
