### TARGETS ###

### PROBLEMS ###
N1 worked almost effortlessly except for a need to spiral search the target. Got star on PAVO.

S1 was not working. Its elevation drive acted like a merry-go-round and could not stop via the server terminal nor the S1gtk. It has to be powered off to stop it by force. Did this 3 times before giving up to try S2.

S2 sidcon had problem communicating with the siderostat.

S3 was the best of all south siderostats. But it had trouble finding the target with the acquisition camera. The sidcon should have a status indicating any on-going spiral search. The spiral search took such long time to remind the user. Star not found!

The WLF between PAVO and S/NAC was lost when checked. Found them again after a quick tweak at NAC-Z.

I think I accidentally pressed the 'RESET ORG' button in the ACQLABJACK gtk
when trying to do spiral searches. After a break to try to observe the
auto-collimation LED on PAVO by moving the sids to az:0 and el:0, I can't get
the star onto the acq camera using N1 anymore.

Due to lack of the following skills, I could not fix the alignment problem this evening:
- save pointing offset of a siderostat after a spiral search found the target star
- perform auto-collimation alignment with PAVO and siderostats
- what is the test star (HR99XX) to be used for auto-collimation
