I finally finished going through the S2 LLO elogs to look for bad
stretches. I attach the text file for submission to the appropriate
DataQual site.

There are many segments which I think should be thrown out, but they
should be caught by more quantitative investigations (saturations, DAQ
dropouts, and just excess noise).

There's also some several occasions of Cal line mishaps, which should be
caught by running retroactively a lineMon type of thing on the EXC
channels themselves.

What remains is a few days from 4/7 - 4/9 where I suspect the EY GPS cable
had problems. Maybe this is implicit in the Suggested Investigations list
as the 6th Miscellaneous - High Priority item? LLO unfortunately did not
record some of the LSC Diagnostics channels that LHO had for this. It
should be caught by the "LSC Skew" channel.
