Procedures for controlling VAMPIRES cameras.

Readout mode

VAMPIRES has three default modes set for each camera with configurable crops

Standard

This is the standard 3"x3" FOV crop

⛔️ This does not exist yet

vampires mode standard

MBI

This is a 12"x6" crop that accommadates the four 3"x3" fields produced in the multi-band imaging (MBI) mode.

vampires mode mbi

MBI Reduced

This field crops out the 625nm field so that the maximum readout speed of the detector can still reach ~500 fps while still imaging three 3"x3" FOVs.

vampires mode reduced

Exposure time

🤯 Pro-tip: Automatic exposure time calculation

If you have a desired average signal in ADU or electrons you can quickly estimate the required integration time with

vampires get-tint <adu>
vampires get-tint -e <e>

💡 Tip: Automatic readout mode

The slow readout mode offers uncompromised read noise at the cost of slower frame rates, but we recommend switching to it whenever your exposure times cross the threshold for the maximum slow-mode frame rate. This is ~30ms in SINGLE or MBI-REDUCED modes, and is ~60ms in MBI mode.
