Stochastic Hardware Injection Started with 0.1x Amp at 23:29 UTC
J. Kissel, E. Daw In this current lock stretch, I've begun Ed's Stochastic Injection (LHO aLOG 18161) starting at 23:29 UTC. Scared of breaking the lock, I've started with multiplying the whole injection by a scale factor of 0.1. Out of habit, this has gone through the H1:CAL-INJ_TRANSIENT bank instead of the H1:CAL-INJ_CW bank, but signals arising from both banks should result in identical DARM CTRL [ct]. It should last ~10 minutes. The observation intent bit is on.

This injection completed as scheduled. It also reduced our inspiral range by 3 [Mpc]. I'm glad I decreased the amplitude by a factor of 10! Details: I ran the following command from the /ligo/home/jeffrey.kissel/2015-05-02/ directory on the hardware injection machine, h1hwinj1: awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 inj10mins.txt 0.1 -d -d > 2015-05-02_2327UTC_InjectionTest_x0p1.log Here're the exact start and stop times: Channel = H1:CAL-INJ_TRANSIENT_EXC File = /ligo/home/jeffrey.kissel/2015-05-02/inj10mins.txt Scale = 0.100000 Start = 1114644525.000000 End = 1114645111.000000 Duration= 586 [sec] I attach the output of the .log file (renamed to .txt because the aLOG can't handle the ".log" extension).
