Initially fringes was not found with PAVO gain of 170. Later we boost the gain to 200. As a result, found fringes at ~260-290um. S/N ~2.5-3.0. The numbers for tip-tilt mirrors in the status display of PAVO server are seen to fluctuate from ~-0.8 to ~+0.8 at the next instance.

North TT lost its stars more than twice. We had to stop the sid, zoff, re-track the sid and re-acquire the star onto PAVO.

When we run 'endnight', we found that no data were saved!! We looked in argus:/data/110427 (hopefully this is not the right place to look). No such directory exist. There were no indication from PAVO that the data is not saved into hard disk. Our data are lost?

We finally found that our data are being stored in argus:/data/110419 for reason unknown. We discovered this from the time-stamps of the files. We did a 'mv 110419 110427' on argus and rerun endnight again. Phew...
