preparing for hardware injection tests 
I'm preparing to do a set of hardware injection tests. I will update this aLog entry as injections are scheduled.

I first need to svn up the repo to get the injection files. And check that the latest version of tinj is installed.

I am beginning by scheduling one hardware injection first. The schedule was updated with:
1134345924 1 1.0 coherentbbh10_1128678894_
christopher.biwer@LIGO.ORG - 16:05, Wednesday 16 December 2015 (24267)

tinj was enabled at 00:02 UTC at H1.

I did the following checks:
 * I checked the first injection to make sure it was flagged in the segment database. I queried H1:ODC-INJECTION_CBC:2 and L1:ODC-INJECTION_CBC:2 and found that both returned the segment [1134345929,1134345931). This looks good, it is what I expect.
 * I checked the tinj.log file as the injection was being performed. It was logged as successful.
 * I checked the TRANSIENT_OUT16 channel to check that the signal was injected. See attached plot.

Everything looks good. So I'm going to add the following to the schedule:
1134348928 1 1.0 coherentbbh11_1128678894_
1134350128 1 1.0 coherentbbh12_1128678894_

LHO lost lock a couple minutes before the injection scheduled for: 1134348928 1 1.0 coherentbbh11_1128678894_. So this injection only went into L1.

I've removed the lines:
1134350128 1 1.0 coherentbbh12_1128678894_
1134351328 1 1.0 coherentbbh13_1128678894_
1134352528 1 1.0 coherentbbh14_1128678894_

from the schedule since LHO is still trying to relock.

LHO  lost lock again.

The following line was then removed from the schedule file then:
1134358528 1 1.0 coherentbbh19_1128678894_

Added the following lines to the schedule to re-do the injections that were skipped due to LHO losing lock:
1134359800 1 1.0 coherentbbh11_1128678894_
1134361000 1 1.0 coherentbbh12_1128678894_
1134362200 1 1.0 coherentbbh13_1128678894_
1134363400 1 1.0 coherentbbh14_1128678894_
1134364600 1 1.0 coherentbbh19_1128678894_

Just to recap. Tonight tests the following injections are in the schedule:
1134345924 1 1.0 coherentbbh10_1128678894_
1134348928 1 1.0 coherentbbh11_1128678894_
1134353728 1 1.0 coherentbbh15_1128678894_

These injections are now complete.
