HOW TO

No bcu47 mode

When the "no bcu47 mode" is enabled, the WFS software ignores the following devices: bcu47, ccd47, camera lens and tip-tilt. This allows the AOS to send the usual commands (Preset, Acquire, Start, Offset etc) without errors.

How to enable or disable the "no bcu47 mode":

Login on wfsdx and give the following commands from any terminal:

[AOeng@wfsdx]$ enable_nobcu47_mode.sh

[AOeng@wfsdx]$ disable_nobcu47_mode.sh

When the nobcu47 mode is enabled, an indicator appears at the top of the WFS Arbitrator GUI:

Point the star in "no bcu47 mode"

The sequence is modified as follows:
  1. Instrument: send PresetAO
  2. Operator: manually center the star on the pyramid tip. Use the spiral script described below, or the offset buttons on the Wfs Arbitrator GUI.
  3. Instrument: send RunAO

Spiral script

On wfsdx there is a script to spiral the XY stages and record the ccd39 illumination level at each position.

[AOeng@wfsdx]$ stage_spiral.py

Usage: spiral.py

Example: spiral.py 3.0 1.5

will execute a spiral movement with a radius of 3.0 arcsecs from the current point (a 6x6 arcsec range in total) with a step size of 1.5 arcsec

Coordinates refer to the pyramid FoV center.

Modifica tabella AO per LUCIFER

Pupille shiftate

mettiamo le pupille shiftate a bin2 e bin4
  • bin2: 20150424-194620 invece di
  • bin4: 20150424-204203 invece di

Ricostruttori BIN2 a 100 - 120 modi

Il rec "ufficlale" e' il 20130916_221257, fatto con la intmat 20130916_220905. Dalla stessa intmat facciamo due ricostruttori:
  • bin2 100 modi: 20150504_085431
  • bin2 120 modi: 20150504_085630
Mettiamo inizialmente in tabella il 100 modi.

Il rec a bin4 puo' rimanere quello solito (36 modi)

Rimozione bin1 e bin3

Dato che a bin1 il loop non chiude, lasciamo il bin2 anche per le stelle brillanti.
Togliamo il bin3 per il quale non abbiamo la configurazione e non e' stato provato.

Tabella badseeing

La tabella badseeing diventa uguale a quella normale, che comunque non chiude piu' di 100 modi.

Le tabelle originali sono state salvate col suffisso ".2015a"
