Today we did HEPI injections on all BSCs. We did beam direction and a couple in the rotational DOFs. We did a band 1-5Hz, a band 10-400 Hz and a 1.55 Hz line. Attached are examples from ETMY.

Dtt files for all can be found in: /ligo/www/www/exports/pem/19aMarPEMinjections/LHO/HEPI/.

Unfortunately the DARM noise 18-40 Hz is high today, as noted last night, so maybe we'll have to redo some of these tests later.

Referenced traces are quiet = no-injection.
