Introduction to SIS
The SIS manual is available [https://dcc.ligo.org/cgi-bin/private/DocDB/ShowDocument?docid=160 here].
Getting started
SIS is available on a couple of the control room machines and on menkar.ligo.caltech.edu (fast).
There is a SIS directory on the 40m SVN which contains some ongoing work on e.g. LG33 beams.
