Pedestal, how many frames does it remain constant?

Data from a single pixel on APS-3 #2

Voltage out as a function of time after reset

Remove the first couple of points and fit to a polynomial

Current from polynomial fit

pedestal values in electrons for 4 ms integration time

deviation from pedestal for 4 ms integration
shown as number of electrons

Conclusion: one can read 35 frames before reset and still use a single pedestal.

This, however, is a voltage dynamic range of only 100 mV
