Waveforms-Overshoot

4-13

NOTE


The calculated exposure time for this 100
millisecond exposure, taken with a ten millisecond
delay, is now correct and the overshoot at the
beginning of the exposure has been skipped. The
waveform is now only 90 milliseconds in length
because the NERO mAx delayed data acquisition
for ten milliseconds.
