Hello, I am trying to measure multiple locations across a line-space grating sample to basically get a height profile over a relatively large area. However, I am finding that if I measure a number of locations in a row and then return to a previously measured location I will get different height results. Basically, an individual scan looks something

Below are two examples. Thanks! Original 1: Crop 1: Original 2: Crop 2:

Sometimes when I crop a scan I find that the new cropped version has a different height scale. Specifically, I am looking at step heights and sometimes the scan will include junk that I want to crop out, but when I do so the step height can change significantly. After cropping I have seen step height decreases (e.g. 60 to 40 nm) and increases (e.g.
