Transient injection system tested

Evan G., Keita K., Jamie R., Dave B.,

We tested the transient hardware injection infrastructure to make sure that we could still run transient hardware injections. While the IFO was not in low noise, we successfully made a DetChar set of injections. These were injected starting at 1233537100. We saw the injection on the TRANSIENT filter bank and on the PCALX RX PD. The STATUS did change from 3 to 40 and back to 3. The value was displayed weirdly by DTT, ndscope and dataviewer, possibly because it is a uint32 data type, but we believe it is doing the right thing.

The obs_channel_name variable in INJ_TRANS.py had to be updated to "GRD-IFO_INTENT".

Since some of this work involved redefining the directory structure on h1hwinj1, I have recreated the RELEASE sym link to point to preO3_H1 and have restarted the CW injections to verify things still work, which they seem to do (see attachment).
