Night logs and results

4/3/07 UT
Thick to patchy high clouds and excellent seeing (~0.75" in V). Boresighted LLT and checked image quality (<1.2" FWHM stars, ~1.6" FWHM LGS). Much debugging of laser and BTO. Major problems with the AO telemetry system. Debugged acquisition procedures and achieved K Strehl=24% on a bright LGS target despite clouds and low laser power (4-5 W). Night log (pdf)
