Looks good to me. Re the example run, you report: INFO:desi_fvc_proc:259::rms(measured-expected)=0.0161mm rms(corrected-expected)=0.0029mm where 2.9 microns sounds really good. Is that a turbulence only run (i.e., no repositioning)?

yes. and 16.1 microns instead of 10 micros because of turbulence in both images.
