Greg, Sheila and Dave
Peter Fritschel asked us if we could get a sense of which channels were compressing well in the frame, as part of the decision making of which channels should go into the science frame. Greg wrote a script which calculates the compression rate on a channel by channel basis. To keep the numbers manageable we limited the channels to those with acquisition rates of 1024 or higher.
Sheila suggested a time where the H1 IFO was in its best state to give our most realistic compression rates. The time chosen was 1am PDT Friday 31st October, GPS time 1098777600.
The results are appended as a text file showing 2918 channels (name, acquisition rate, compression ratio).
Also attached is a histogram plot showing the distribution of the compression rates.
