Notes:
- The column marked 'range' shows the chosen count-level domain over which the peak-to-peak linearity is measured. The top of the range is close to 'full-well'.
- The LEDs are bright, and linearity for low count-levels, below 500 ADU, is difficult to measure.
- Exposure times range from 0.002 to 12 seconds.
- The exposure-time correction needs to be added to the requested exposure time for the low-count-level range linearity to appear flat as a function of counts.
