Pylinac image

I need the articles that pylinac use to calculate and their tolerance: Uniformity and low contrast visibility.
I want to add a test. Would you like to show me how to do it?

Here is the class for the CTP486 HU Uniformity:

Here tolerance is set using analyse() (default is 1 for low contrast tolerance and 40 for HU uniformity and linearity tolerance):
