where *Ein* is the initial PI value of the event, *Eout*
is the final PI value and *rate* is the number of electrons per
second observed in a
particular column at a given time. The coefficients, a0, a1 and a2 have
been calibrated using in-orbit data and are different for Timing and Burst
mode.
The number of electrons is derived from the total PI charge deposited
on the column at that time.
