1. CCD readout noise: integration time 10ms, CCD readout noise root mean square;

2. CCD dynamic range: the dynamic range is the saturation value of 2ms integration time/the root mean square of CCD readout noise, the evaluation method refers to the standard of enterprise;

3. Response linearity: The response nonlinearity is before calibration.
