Last night I ran a longer version of the full magnetic injection suite starting at about 03:10 UTC, and it finished at 07:33 UTC. This used the same parameters as last week's run, except I doubled the injection time to 5 minutes each.
Exact times and injection parameters are in the usual log directory for the magnetic injections: /ligo/www/www/exports/pem/WeeklyMagneticInjection/logs/1448075483.txt
