Should have used 100mV range for ADC. The saturation below 100m doesn't matter.

analyze data, find the channel 5 could be misaligned because ch2 is more consistent with model, then align both lasers with big telescope

align 291 again

The data before 18:00 look having problem because channel 1 data/model shape is different with that of channel 2.
