I noticed that the graph generator http://andrew.triumf.ca/beacon2/history/loss.html was getting extremely slow - it scales as the number of active (and recently active) beacons. I have made a minor change to speed up the script by a factor of 5 or so. It's still rather inefficient - searching through flat files for (S,R) lines.
