K2 raw frame saving¶

1. Typical frame saving preset parameters for counted/super-resolution: 0.2 s frame exposure time, 4-5 s total exposure time at 8-10 e/physical pixel/s (Some argues that 5 e/physical pixel/s is better). You can use DM's reading of dose rate while it is in counted mode and UNBINNed to get a reasonable estimate.

Camera configuration for frame saving¶

1. "Exposure time" specifies the total time in which the frames are saved.
2. "Frame time" defines the length of each frame. The minimal value is 50 ms for K2 Summit and the values must be multiple of 50 ms.
3. "Frames to use" is not used
4. "Readout Delay" is not used
