Feature: Peeko/TT Peeko

Feature: Peeko/TT Peeko (with WFS in Pyramid position 2020-10-27)

Starting Peeko

1. In workspace, click left mouse button. Select Peeko from resulting menu.
2. user@real.ucolick.org > peeko
3. Acquire new background: WFS camera dark/dark()
4. Recommend set automatic display scaling: drange('auto').
5. Recommend: zoom().
6. Recommend enable overlay: alines().

Starting TTPeeko

1. In workspace, click left mouse button. Select TTPeeko from resulting menu.
2. user@real.ucolick.org > ttpeeko
3. Acquire new background: TT camera dark/ttdark()

Peeko Commands

 
   mode='16x'         -- sets Peeko defaults for 16x mode 
   mode='8x'          -- sets Peeko defaults for 8x mode 
   zoom()             -- set the wfs and inten displays to zoomed 
   alines()           -- overlays aperture guide lines 
   wfs_only()         -- display only the wavefront sensor 
   all4()             -- show all the displays (counters wfs_only()) 
   drange()           -- set the display range for one or all displays 
   e.g. drange('auto') 
   e.g. drange('woofer','auto') 
   e.g. drange('wfs'(1500,55000)) 
   -- Adjust WFS display between lower (e.g. 1500) and upper (e.g. 55000) cut. 
   e.g. drange('inten',(0,10000)) 
   -- Display intensity grid. 
   e.g. drange('woofer',(-1,1)) 
   -- Fix display range 
   exit()             -- exit the display 
    
   wfs_br()           -- replaces the obselete wfs_bg() Background removed 
   wfs_bg()           -- change the wfs display from raw to background-remomved 
   wfs_raw()          -- shows raw counts in WFS display 
   wfs_ma()           -- shows moving average in WFS display 
   wfs_mabr()         -- shows moving average, background removed in WFS display 
   wfs_maff()         -- shows moving average, flat fielded 
    
   pick()             -- place indicative box in TT Peeko display 
   hist()             -- display a histogram of the actuator values 
   stats()            -- reports the number of saturated actuators 
   help()             -- get help on peeko commands 
   state()            -- print the state of the real-time code 
   unzoom()           -- set the wfs and inten displays to unzoomed 
   update()           -- set the update interval, in milliseconds 
   sethost()          -- set the host machine 
   start()            -- start (or restart) the peeko display 
    
   connect()          -- connect to the real-time code (same as restart) 
   fid()              -- turn on or off fiducials 
   cmap()             -- change the color map for one or all displays 
   

TT Peeko Commands

 
   display('tts')    -- basic display 
   display('tts_ma') -- moving average 
   compass()         -- display a compass indicator for TUB=74 
   compass(X)        -- display a compass indicator for TUB=X 
   hide_roi()        -- Remove overlay region of interest (box). 
   show_roi()        -- Overlay region of interest (box). 
   

Re-size Region Of Interest (ROI) Box in TT Peeko

>>> tt_roi()

To re-size the region of interest, the following convention is used:

>>> tt_roi([xcen,ycen],[xdimension,ydimension])

For example:

>>> tt_roi([49,37],[10,10])

A limitation demands that even numbers MUST be used for box dimensions.

Change Log:

2022-01-21: Startup of peeko set to automatically do wfs_br() and alines() and ttpeeko to do display(’tts_br’) and compass().

2017-10-06: Updated Region of Interest instructions.

2014-05-13: First version.
