Dear Peter !
Concerning Eh and Evh thresholds we can only estimate ones
using the information from FADC data for muon track and mu-capture events.
We used the spectra of maximum amplitude in events for these estimations
and Gena's signals from pulser for calibration.
Our estimation for Eh is about 70 keV,
for Evh about 270 keV. The accuracy these estimation ~10%.

Available information of FADC analysis are in Oleg's messages in e-log
(Run8 and Run8 -analysis)
