 I wanted to add reporting of MTF at 5% and 1%, values which are not reached in the MTF tree I was using, I therefore tried to extend the x-axis of the graph by increasing "Points in Final PSF" in the properties from 32 to 100. 

-This works in that my y-axis extends to 6 lp/mm, but the reported MTF value for 0.1 also changes, from ~1.2 to ~0.85, and it appears to scale with the number of points chosen. There was also a small (but less significant) change to the reported 0.5 value.

 If this is an obvious effect of changing the number of points then my apologies, and please close and ignore this ticket! Thanks
