Dear collaborators,
I will try to summarize what has happened in response to my "call to 
action" of last week.
This is  a brief summary of what I know, and if there is anything left 
out, it is more likely due to the
early hour than to ill will.
GEOMETRY:
The best available description of the exp. is in the db.  Some 
"finetuning" is being done in Krakow (using tracking), though the final 
description may need to wait until more surveying can be done.
CALIBRATIONS:
PEDESTALS
     CEJ has kindly been volunteered.  He has implemented some detectors 
that were not, and is starting a systematic pass 	through the data set.
BB:
	 SZ has looked at some calibrations.  The "gain" calibs may be a bit 
more tricky than before since we calibrate on the 	1 MIP peak, but our 
data are biased to central events.  I noticed this on an early run I 
tried to calibrate, it is possible to 	set the fit range (per tube) to 
get the 1 MIP (which will not necessarily be the most intense peak).  
The scripts for doing 	these calibs exist together with the  TOF 
subsytems, so these efforts need to be coördinated
TOF:
	DO is tesing existing scripts
RICH,C1,C4:
	CEJ has volunteered for this as well, so I hope FV doesn't give him 
too many shifts...
CENTRALITY:
	This is "essentially" done, and checked in for an early run(SS).  
Needs to be checked for a later run(IGB)
DCs
	DC calibrations are underway in Krakow
ZDCs
	Will be started in about 2 weeks (MM)
TPCs
	IGB promised scripts and documentation by the end of the week.  Of 
course, he was referring to the fiscal, not the 	calendar, week.  So, 
technically, the promise has not yet been broken.  The scripts work, 
there are nice utilities for
	obtaining graphical output of the results.  The scripts need to be 
collected, the documentation updated, and the whole
	made public.

That is what I can think of early Monday morning.  Comments are welcome,
happy calibrating,
Ian Bearden
