Standard BS9107 open and closed loop

08:54 Preset to standard BS9107.

• we did dice5 in 3 filters (JHK)

09:18 Preset close loop BS9107. Failed.

• Preset to AO system failed. Star not found.

===> Error in irc_runao
        err = Resmsg[0]  = RunAO result status: Error
        err = Resmsg[1]  = RETRY: No stars found in TV frame (-20001) WFSARB_STAR_NOTFOUND
        err = Resmsg[2]  = AcquireRef[437] failed - RETRY: No stars found in TV frame (-20001) WFSARB_STAR_NOTFOUND

• preset failed again - star not found and I get error: ===> Active Optics loop is not running
• the star was transiting... maybe that's why we see the target at the edge of the Pisces detector (x,y: 400,54)
• send preset again - probably the guide star is too close and it is vignetting the AO guider... so we cancel the preset and try again with another GS.

09:41 Before starting the dither pattern, we realised that the AO internal focus had to be changed for the filter used.

• at this moment using AO before every filter change we need to resend the preset after inserting the correct AO focus.
• for the 3 filters in closed loop we will do: preset - dither - change filter - preset - dither.

10:11 repeat BS9107 in open loop

• during the previous set the star was transiting and some images are elongated
• we repeated all 3 filters with a larger dither pattern
