Hi Flemming, for 2022 there are no changes for the east side resistors.
MySQL [Calibrations_tpc]> select beginTime,ring,resistor,MissingResistance from Geometry_tpc.tpcFieldCageShort where beginTime > '2021-10-01' and beginTime < '2022-12-31' and side=0 order by beginTime;

Thanks Yuri,
maybe another related question. As the resister short was only on the
west and the
added resistor was on that side. Are the East parameter unchanged
between FF and RFF ??
