Problems: 

 







The cause of the 4map main application not starting was the absence of the
DDS service daemon. Most probably when the machine was rebooted the DDS
service daemom died unexpectedly leaving a lock file behind. When 4map
start up script is executed, it checks if the DDS service daemon is
running and if it is not it starts it up. The presence of a wild lock file
produce the script to believe the DDS service is running but the 4map then
fails inmediately when trying to connect to the daemon and dies.

By manually forcing the stop od the DDS service and thus erasing the wild
lock file, and then restarting the service the DDS was left in a working
condition. After that the start up script connected without problems to
the daemon.

The start up script was modified to stop and start the daemon without
asking if necessary from now on. It is less than optimal but it will work
until a more elavorated solution is put in place.

---- 2nd half:

- pointing offsets were large (~10 arcmin)

- ObserverConsole keeps crashing / showing different displays on observer1/2

Comments: 

2nd half:

- Had to figure out how to reset hexapod to standard configuration.

- Seeing briefly below 0.8"

- Cirrus clouds from ~4:30

- Wind from the south
