      3  [[TracNav(GraspContents)]] 
      4   
      5  ||Command:||'''celldes'''|| 
      6  ||Contexts:||Network socket, serial console.  Applies only if the CCD is an "OTA" device.|| 
      7  ||Function:||Designates the intended function for each of the 64 cells.|| 
      8  ||Required Parameters:||'''cells'''=(64 S/V/D characters)|| 
      9  ||Optional Parameters:||'''dev'''='''all'''|'''0'''|'''1'''|| 
      10   
      11  The string of cell designators must be a sequence of '''exactly 64 characters''': 
      12   
      13  ||'''S'''||Designates Science readout use|| 
      14  ||'''V'''||Designates Video readout during exposure(*)|| 
      15  ||'''D'''||Designates a Dead cell which should be electrically floated|| 
      16   
      17  Order of the cells is row-major listing of the Catesian coordinate system of cell positions. 
      18   
      19  Usage for the cells: 
      20   
      21  ||xy07||xy17||xy27||xy37||xy47||xy57||xy67||xy77|| 
      22  ||xy06||xy16||xy26||xy36||xy46||xy56||xy66||xy76|| 
      23  ||xy05||xy15||xy25||xy35||xy45||xy55||xy65||xy75|| 
      24  ||xy04||xy14||xy24||xy34||xy44||xy54||xy64||xy74|| 
      25  ||xy03||xy13||xy23||xy33||xy43||xy53||xy63||xy73|| 
      26  ||xy02||xy12||xy22||xy32||xy42||xy52||xy62||xy72|| 
      27  ||xy01||xy11||xy21||xy31||xy41||xy51||xy61||xy71|| 
      28  ||xy00||xy10||xy20||xy30||xy40||xy50||xy60||xy70|| 
      29   
      30  Is sent in the string in the following order: 
      31   
      32  cells='''xy00 xy10 xy20 . . . xy67 xy77''' 
      33   
      34  An actual command selecting all cells on "dev 1" but using xy11 for video would look like: 
      35   
      36  {{{ 
      37  celldes dev=1 cells="SSSSSSSSSVSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS" 
      38  }}} 
      39   
      40  (*) CCD readouts, video or science, are "destructive" so a even though a "V" cell still gets included in the final readout, there is no valid image data. 
      41   
      42  === Notes: === 
      43   
      44  If dev= is omitted, the last default dev applies (which can be either 0 or 1, but not "all"). 
      45   
      46  The FITS header for each exposure contains a nice self-documenting map illustrating which cells where video or floated, in addition to the 64-character keyword value '''CELLDES'''. 
      47   
      48  Various image displays may be rotated or flipped to match sky!
