While at Hanford I developed some python software that can make a series of injections automatically.  
This was useful for taking measurements overnight, or running the same series of injections over and over with small adjustments (like bandlimited frequency noise injections over five bandlimits).

Jenne has asked for some documentation, so I'm writing it up in the git.ligo.org README below.  This will only be useful for front-end machines at LHO in it's current state, but only small modifications would make it work at LLO or CIT. 
Step-by-step instructions on git.ligo.org

Only one example plotting calibrated ASDs and TFs as of now, April 18 2019, but will be adding more soon, including writing injection suites like the one in MCL_injection_caller.py
