PEM injections after 17:30 UTC

After 17:30 UTC the interferometer was not undisturbed: I was making PEM injections.

The interferometer has been locked undisturbed for several hours in low noise before Robert started his injections.

The range degraded slowly over time, and it has been polluted by some huge glitches, similarly to what has been observed in the past.

It turns out that the range was degraded by a changing ISS coupling during the lock. 
Evan and Matt had left the ISS second loop open, as they were having problems with it.

You would see a plot with the a DARM spectrum at the beginning and at the end of this lock, showing large peaks appearing in DARM (a factor of a few above the noise floor), if DTT hadn't crash on me twice while trying to save the plot as PDF...
