Instrument operation and data handling

The CCD camera is a slave of the telescope and controlled from within SCS. Its moving parts are the shutter (BMK internal “8 slide” shutter) and, optional, a filter slider with two positions (tbd). The filter slider is foreseen to hold a Johnson V and I filter of diameter 150mm (tbd). The CCD controller is optimized for a realistic speed-times-RON product and its current RON is 4.5 electrons rms in 50s read-out time.

Instrument operation also includes data file management. It starts with the creation and transfer of the raw FITS files from the controller (including Meta data) to a local host computer, the archiving (mirroring) on a second machine, and the immediate transfer via a 1GB/s connection to the STELLA or GREGOR control room (tbd). Here, details are to be determined but we follow the outline in Fügner, Fuhrmann & Strassmeier (2009, AN 330, 330).
