Hi Frans, Thanks again for your response. In the paper they convolve the slit with the presample blur of the sensor and then sample it. Having reread the paper I think this is what I need to do - I was hoping that mtf_generate_rectangle might offer a shortcut for doing this, but from your explanation above, I don't think that it will. I've attached the paper for your interest. Kind regards, Dean.

Hi Frans, Thank you very much for this, as well as the ChatGPT tip, as I have struggled to get Gawk working on Windows. One further question... One of my aims is to replicate the work described in "Comparison of tilted slit and tilted edge supperresolution MTF techniques" by Olson et al. (2007). My plan is to create a narrow slit using the generator - do you think this will work? Thanks in advance, Dean.

Hi, I've been using mtf_generate_rectangle to generate rectangles, but I'd like to generate more complex charts and see usaf1951r.txt mentioned in your blog. However, I cannot find this file in the distribution or on SourceForge and think it would act as a good starting point for my own charts. Can you supply this and the Siemens example? Thanks, Dean. PS I'm working on Windows.
