Running magnetic injections in concert with LLO

JoeB and I picked a time, and we're running /opt/rtcds/userapps/release/pem/h1/scripts$ python inject_mag_10to40.py (attached here with the current gps time we used).

I also made sure that our amplifiers were on (I think / hope) via the medm screen, which I've also attached.

Injection was succesfull.

Fig1 &2: Hx magnetometer - Lx magnetometer: Coherence/CSD, before, during and after injection

Fig3 &4: H strain - Lstrain: Coherence/CSD, before, during and after injection

 

Channels used:

Hx mag = H1:PEM-CS_MAG_LVEA_VERTEX_X_DQ

Lx mag = L1:PEM-CS_MAG_LVEA_VERTEX_X_DQ

H strain =H1:GDS-CALIB_STRAIN

L strain = L1:GDS-CALIB_STRAIN

Times used:

Before: start: 900sec before injection - duration: 300 sec, 10 sec fft, 50% overlap

Injection: start gps = 1372010416 (June 28 - 17:59:58  UTC) - duration: 300 sec, 10 sec fft, 50% overlap

After: start: 600sec after injection - duration: 300 sec, 10 sec fft, 50% overlap
