Questions - We systems were recently asked about what the current Power Limit into the Mode Cleaner was and if there was a document what was the link? LHO specifically wanted to flash the mode-cleaner in air with 200 Milli-Watts. 

Links - The document is M1300464, link is https://dcc.ligo.org/LIGO-M1300464, the relevant sections and limits are 4.1 (in air) and 4.2 (under vacuum).

Answer - As per section 4.1 of M1300464 200 Milli-Watts in air is acceptable.

Reference - I note that LLO currently have the "clean" Mode Cleaner at 2.3 W (under vacuum) as per LLO alog entry: - https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=13209 and as per section 4.2 of M1300464 that this is also acceptable. 

Action - LLO have been asked (in e-mail by Calum) to re-measure the absorption as per section 4.2 of M1300464. (They LLO have already been doing this recently, refer to https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=13109.)
