ETMX In-Charge Measurements
Today at around 5:40P.M Georgia and I ran the In-Lock Charge Measurements for ETMX.
We switched the DARM control to ITMX.
Then we ran the script run_charge_ETMX.py that is located in
cd /opt/rtcds/userapps/trunk/sus/common/scripts/quad/InLockChargeMeasurements/
In which we took the measurements for ETMX,ETMY, and ITMY at 1343177340 that are all saved in
cd /opt/rtcds/userapps/trunk/sus/common/scripts/quad/InLockChargeMeasurements/rec_LHO
Then, after taking the measurements were taken and we were switching the DARM control back to ETMX fomr ITMX we lost lock.
I have run the analysis for the In-Lock Charge Measurements for ETMX,ETMY, and ITMY.
Ran through process_single_charge_meas_mayra.m (On my desktop). Unsure about the results.
ETMY:
alpha: 3.0353e-10 , beta: -2.5052e-08, beta2: -2.0853e-08, gamma: 1.2082e-10
ITMY:
alpha: 3.1314e-10, beta:-5.8032e-10, beta2:-7.3756e-10, gamma: 4.3867e-10
ETMX:
alpha: 2.7794e-10, beta: -3.1116e-08, beta2: -4.40006e-08, gamma: 1.1169e-10
I have ran the analysis code again in
cd /opt/rtcds/userapps/trunk/sus/common/scripts/quad/InLockChargeMeasurements/process_single_charge_meas.m
The mesurements that I got for the four coefficients are (
ETMX:
alpha: 2.779442e-10, beta: -3.1116e-08, beta2: -4.40056e-08, gamma: 1.116938e-10
ETMY:
alpha: 3.03528e-10, beta: -2.50518e-08, beta2: -2.08529e-08, gamma: 1.20815e-10
ITMY:
alpha: 1.9571e-11, beta: -1.45080e-10, beta2: -1.84390e-10, gamma; 2.74167e-11
These seem to make more sense then the previous ones
