Pulse shape vs dose

Ipre = 200µA
Isha = 100µA
Ibuf = 100µA
Icomp= 50µA
Ipipe= 40µA
Isf = 100µA
Idrv = 90µA
Vfp = +0.2V
Vcomp= -2.0V
Vfs = +1.5..+0.25V
Vd = -790mV
Vdcl = +960mV
Voffs= -650mV
The test pulse injection had a bug yielding the undershoot
Ipre = 200µA
Isha = 100µA
Ibuf = 100µA
Icomp= 50µA
Ipipe= 40µA
Isf = 100µA
Idrv = 90µA
Vfp = +0.2V
Vcomp= -2.0V
Vfs = +1.5..-0.125V
Vd = -933mV
Vdcl = +1.53V
Voffs= -353mV
The test pulse injection had a bug yielding the undershoot
Ipre = 200µA
Isha = 100µA
Ibuf = 100µA
Icomp= 50µA
Ipipe= 30µA
Isf = 100µA
Idrv = 90µA
Vfp = +0.2V
Vcomp= -2.0V
Vfs = +1.5..-0.125V
Vd = -1.008V
Vdcl = +1.22V
Voffs= -243mV
The test pulse injection bug was detected and removed and the undershoot was gone.

The undershoot seen in previous pulsescans is caused by a distorted test pulse signal: It had an exponentially falling flank instead of being a perfect step function. With the correct test pulse signal, the undershoot is (almost) gone
