h1. K2 raw frame saving 

 # 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. 

 h2. Camera configuration for frame saving 

 # "Exposure time" specifies the total time in which the frames are saved. 
 # "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. 
 # "Frames to use" is not used 
 # "Readout Delay" is not used
