Optimization of EMCCD operating parameters for the acquisition system of SPARC4

نویسندگان

چکیده

We present the Optimization Method for Electron Multiplying Charge-Coupled Devices (EMCCDs) of Acquisition System SPARC4 (OMASS4). The OMASS4 uses as figures merit signal-to-noise ratio (SNR) and acquisition rate (AR) a function operation mode CCDs. Three different modes optimization are included in OMASS4: (1) SNR only; (2) AR (3) both simultaneously. first two calculate an analytical maximization cost whereas third bayesian method to determine optimum operation. apply find observations obtained at Pico dos Dias Observatory, Brazil, compare delivered its performance with ones adopted by observer. If had been used tool optimize CCDs all these nights, it would be possible improve their efficiency 97.17 %, 65.08 77.66 % 1, 2, 3, respectively.
