13/13Summary

• LSC (DuoTone) results indicate stable timing performance – ToDo: cumulative database for S5 LSC timing

• Summary of timing information on auxilary channels is available on the web

• Summary of long term timing hardware comparison information is available on the web

• Hardware parts presently studied for Advanced LIGO are promising
