varyperiod¶
- marxs.design.tolerancing.varyperiod(element, period_mean, period_sigma)[source] [edit on github]¶
Randomly draw different grating periods for different gratings
This function needs to be called with gratings as parameters, e.g.
>>> from marxs.optics import CATGrating >>> from marxs.design.tolerancing import varyperiod >>> grating = CATGrating(order_selector=None, d=0.001) >>> varyperiod(grating, 2e-4, 1e-5)
and the parameters are expected to have two components: center and sigma of a Gaussian distribution for grating contstant d.
- Parameters:
- element :`marxs.optics.FlatGrating` or similar (or list of those elements)
Elements where uncertainties will be set
- period_meanfloat
Center of Gaussian (in mm)
- period_sigmafloat
Sigma of Gaussian (in mm)
