1. For the image analysis (IA) a star with should be used.
   1. use AG stella to select the star
   2. GP1 A/B Center field (TCS panel)
   3. In "NTT Pointing and Centering" panel:
      

      AG Ref Light (IA)

      ->

      GP/Nolog

      ->

      Pick Object

2. In AO workspace:
   • Maximum counts in AO panel has to be > 10000
   • integration = 10sec if star has m=10
   • psg actconControl
     • is it running?
       • NO: msgSend ``''actconControl EXIT''''
3. apply AO or not?
   none
   M2
   M1 and M2 [ only if excellent, ]
   + differential

4. STORE

   ->

   ONECAL

   (only for absolute! If bad seeing or airmass)
5. but

   STORE

   ->

   SEQAO

   (normal operation)
6. then look at counts, if low (<10000) ->

   STOP

   , then change exptime->

   SEQAO

7. Error message must be

   OK

   at the center of the screen
8. Look at M1 forces updating
9. if def. bad ( > 0.0x), and/or fitting residual > 0.1, then ->

   SEQAO

10. if altitude changes by then repeat IA
11. 

Auto Guiding

1. Workspace is Adapter/Lamps
2. After finishing the IA, one goes back to the guide star, so the following must be seen in the panel
   • RU turret must be

     fully open

   • Dichroic must be

     dichroic out

3. pick object -> box to star (or star to box)

Troubleshooting

• ROTATOR ERROR:
  • Look at logmonitor: if error is of ``servo'', then in screen wt5tcs:0.1 the rotator is likely in STANDBY. So put it ONLINE.
  • Otherwise it went into limits, and in that case there is a procedure, but the dirty way is:
    1. stop TCS
    2. start TCS
