||Command:||'''celldes'''|| |
| 4 |
4 |
||Contexts:||Network socket, serial console. Applies only if the CCD is an "OTA" device.|| |
| 5 |
5 |
||Function:||Designates the intended function for each of the 64 cells.|| |
| 6 |
6 |
||Required Parameters:||'''cells'''=(64 S/V/D characters)|| |
| 7 |
7 |
||Optional Parameters:||'''dev'''='''all'''|'''0'''|'''1'''|| |
| 8 |

The string of cell designators must be a sequence of '''exactly 64 characters''': |
| 9 |
9 |
||'''S'''||Designates Science readout use|| |
| 10 |
10 |
||'''V'''||Designates Video readout during exposure(*)|| |
| 11 |
11 |
||'''D'''||Designates a Dead cell which should be electrically floated|| |
| 12 |
12 |
Order of the cells is row-major listing of the Catesian coordinate system of cell positions. |
| 13 |

Usage for the cells: |

Is sent in the string in the following order: |
| 23 |

cells='''xy00 xy10 xy20 . . . xy67 xy77''' |
| 24 |

An actual command selecting all cells on "dev 1" but using xy11 for video would look like: |
| 25 |
25 |
{{{ |
| 26 |
26 |
celldes dev=1 cells="SSSSSSSSSVSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS" |
| 27 |
27 |
}}} |
| 28 |
28 |
(*) 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. |
| 29 |

=== Notes: === |
| 30 |
30 |
If dev= is omitted, the last default dev applies (which can be either 0 or 1, but not "all"). |
| 31 |

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'''. |

Various image displays may be rotated or flipped to match sky! |
