Dear Dr. Weigelt:
according to recent experiments we made I would suggest to apply a chin rest
during subject's calibration. It seems to be difficult for many people to
maintain the head in a fixed position which is neccessary during this phase.
Regards
Morten Grandt
P.S. Regards to your colleague, Martin Schütte
