2. LIGO-G050197LSC Collab. Mtg, LHO, August 16,20052 S4 DQ Segment Overview Currently version 7 segments »V0 raw locked segment list. »V1 - V4 prepared at the end of each week of running »V5 - V7 created as new info available »~40 segment types defiend for S4 (new record!) »Segments added by hand (thanks Keith) – This will change? »http://gallatin.physics.lsa.umich.edu/~keithr/S4DQ/ Contents (classification) »No Data / Not Science run. »IFO not working »Injections (junk we put there) »Physical environment (junk from outside) »Noise seen only in GW channel (junk from unknown source)
