Drift Chamber Group;
Elliott Wolin has requested each of the detector groups to supply him with
a list of the iformation which should be written to tape or to and online
data base at begin run time. There may be some overlap with the offline
data base and perhaps even with the code management system, but it's felt
that a little redundancy is preferable to not recording vital information.
As a first attempt, I've made the following list. Please post any changes,
additions or objections to this list which you have.

information where obtained
Vthreshold(360+ ADB boards) ASCII file filled by hand
GPIB pulser Tdelay(3 regions) "
FASTBUS lookback time "
HV settings (720 channels) from EPICS eventually (for now?)
translation tables more appropriate for CVS or offline db?
Gas parameters (O2,H20, mix, etc.) from EPICS
Tmax (laser chamber) communication with LABVIEW program
--------------------------------------------------------------------------

Anything else?
regards, Mac
