Turning CW injections back on at H1
Chris, Patrick

I am going to turn the CW injections back on at H1.

We are currently in single-IFO mode right now. And since this is the first time we are going to turn these back on, as a precaution I will ask Patrick (the operator on shift) to turn the intent mode off. The intent mode should only be off for a couple minutes at most. I will make an aLog entry when this work is done and the intent mode is back on.

To do this we will:
  * Turn the intent mode off
  * Turn off the output of the continuous injection filterbank More specifically turn off INJ_CW and INJ_HARDWARE. There is a startup transient in INJ_HARDWARE that we do not want to enter into the ESD
  * log into h1hwinj1/ on a work station browser
  * start psinject using the monit web interface
  * After a short time (a few seconds) turn on the output of the continuous injection filterbank so we don't inject the startup transient
  * Turn the intent mode back on

Patrick is turning the intent mode back on now. The CW injections are on.

I've attached a 10 minute timeseries of HARDWARE_OUT_DQ after the CW injections have been turned on, and it looks like we are using the correct makefakedata_v4 version, ie. 1/20s glitches do not show up in this channel.
