I have semi automated the analysis of the high frequency roaming lines. The timestamp for these roaming lines can be found here: LHO alog 53624
The scripts used to obtain the data and convert it into appropriate format for processing lives here: svn/aligocalibration/trunk/Runs/O3/H1/Scripts/HighFrequency/
The results are saved at the following location: svn/aligocalibration/trunk/Runs/O3/H1/Measurements/HighFrequency/
The instructions on how to run the code can be found in README file here: svn/aligocalibration/trunk/Runs/O3/H1/Scripts/HighFrequency/README
The four high frequency sweeps listed in LHO alog 53974 (the last one has not finished yet) have been analyzed and the data is in the svn at following location:
svn/aligocalibration/trunk/Runs/O3/H1/Measurements/FullIFOSensingTFs/HighFrequencyResults/
The raw FFT data is at the following location:
