The HO algorithm is good enough (no signficant rolloff at wave number 200) at a resolution of 1537x3072.
The bilin algorithm requires almost twice as much resolution to get as good results.
...
Note that in the actual spectra plot, the differences are quite small, with the lower resolution spectra matching very well at low wave numbers, and only slightly below at high wave numbers.
...
The spectra above from single snaphots have a lot of noise which can be removed by averaging. We next analyze how much averaging is necessary.necessary…
