Camera: FLI Aurora AR571
The FLI Aurora AR571, which uses a Sony IMX571 CMOS sensor, is the
modeled science-camera baseline and ETC default. The sensor format and pixel
size are central inputs to the simulator, ETC, and pipeline geometry. The ETC
also supports other camera models for comparison.

Read noise, dark current, frame rate, full well, and cooling performance depend on readout and operating mode. The ETC’s native Aurora model uses 1 e⁻ read noise and 0.002 e⁻ pixel⁻¹ s⁻¹ dark current at -20 °C.
The table gives native-sensor properties, which are also what the simulator’s
FLI_AR571 preset stores. Readout binning is selected on each
InstrumentSimulator instance and in the ETC. The ETC defaults Aurora to
2×2, for which the simulator readout model has 3122 × 2084 output samples,
7.52 µm effective sampling, 2 e⁻ read noise, and 0.008 e⁻ output-pixel⁻¹ s⁻¹
dark current. The native detector definition remains the basis for charge and
saturation calculations.
