CURRENT STATUS OF WORK FOR MC PRODUCTION      18-Apr-03
	=======================================================

	Trigger simulation		M. Palutan, B. Sciascia
	  Done

	EmC geometry			S. Miscetti, C. Bloise
	  Database checked - OK for MC
	  Reconstruction geometry checked - looks good
	  Occasionally hits on plane 6 (!) (of barrel?):
	     1-2 hits per 10 events

        EmC response module		S. Miscetti, T. Spadaro
	  Finished attenuation length calibration on endcaps
	  Needs to preserve CHIT
	  Needs testing
	  
        EmC response survey		S. Miscetti, T. Spadaro
	  Historical consideration:
	    Calorimeter modules: ~200 planes, 500 um thick, 95% Pb 5% Bi
	    This makes X_0 = 1.26 cm, confirmed by shower analysis in data
	  Varying thickness of Pb in MC & reconstructing:
	    MC reproduces X_0 by reconstructed shower analysis if Pb 
	    thickness changed by 80 um
	  N(p.e.) adjusted after X_0 (sampling fraction) fixed:
	    18 p.e./MeV
	  Time resolution adjusted by increasing amplitude of a faster 
	    component of the de-excitation curve
	  Need EMCALIB change:
	    if geanfi version .gt. 172 then use new sampling fraction
	  For pre-production: need to set defaults in MC. Caterina
	    intends to disable cards.
	  No EMCSIMU because that will need tuning

	DC geometry			A. Antonelli, S. Dell'Agnello
	  Done (?)

	DC wire sag map			S. Dell'Agnello, A. Antonelli
	  Most effects recently observed seem to be due to different 
	    underlying angular distributions: have to be careful 
	    with theta cuts when doing these studies.
	  Two executables exist: with '98 and '03 sags
	  No significant difference between these
	  Use most recent sags
	  
	DC s-t relations		P. De Simone
	  Done

	DC dead/hot & efficiencies	M. Moulson
	  Done

	Energy loss in DC		A. Antonelli
	  Need to adjust scale factor in digitization routine:
	  Not just a scale factor, problem in TRACCE routine.
	  Probably fixed, be on the lookout for error messages
	  
	Energy loss straggling of K+/-	S. Bulychev
	  No further developments:
	  Confirmed that Landau model is used
	  Bulychev should make more precise statement of problem 
	    if concern remains
	  Mechanism can be changed with data card if further 
	    study needed

	Background selection		M. Moulson, S. Miscetti
	  All 2001 bgg files produced (except for a very small 
	    number of problematic runs which give 0 bgg events)
	  About 210 of 280 pb-1 of 2002 selbkg histograms generated, 
	    will finish this weekend

	Background insertion		M. Moulson, S. Miscetti
	  Done

	Beam position and momentum	M. Moulson, S. Dell'Agnello
	  No further developments:
	  2001: 138 runs, 6.5 pb-1, of which 
	    48 have statistics too low to obtain values
	      Probably discard, but this should be registered somewhere
	    76 have large spreads in one of Px, Py, Pz
	      Increase tolerance of this value, or discard affected runs
	  Decision at meeting: purge ALL affected runs (138)
	  This needs to be done, will be done together with some 
	    bad runs found in bgg scan (as above).
	  2002: 178 runs from 2002, 25.5 pb-1 
	    Reassess situation after BVLAB results available from 
	    SELBKG histgramming jobs

	Beam energy spread		C. Gatti, T. Spadaro
	  Three values to be used, hard coded by run range
	  Two values (280, 320) for 2002, 1 value (300) for 2001
	  Not yet coded in geanfi.
	  Note: also need to agree on geanfi criteria for goodness of 
	    root-s values, etc. 

	Generator phi/ISR		M. Antonelli
	  Done

	Generator omega -> pi0 gamma	P. Gauzzi
	  Done

	Generator a0/f0 gamma	        P. Gauzzi 
	  Done

	Generator K0 -> pi+pi-gamma	T. Spadaro, C. Gatti, M. Antonelli
	  IB simulation complete, tested
	  Interfacing with GEANT (~half a day of work)
	  To be implemented for pre-production 

	Generator KL3g			C. Gatti, M. Antonelli, T. Spadaro
	  Amplitude obtained
	  Same regularization procedure as for pi+pi-gamma to be adopted
	  1 week of work needed to complete
	  Not to be implemented for pre-production

	Generator KL3g			F. Scuri
	  Tested, 30 MeV cutoff, needs adjustment if we use?
	  Scuri agrees to use Gatti generator when ready

	Regeneration			A. Ferrari
	  All working except treatment of nuclear recoil?
	  Needs testing

	Dalitz maxima for K -> 3 pi	C. Bloise
	  Done

	Generator eta -> pi +pi- pi0	F. Ambrosino
	  Installed. Is it tested?

	BABAYAGA			F. Nguyen, C. Bloise
	  Done

	DB modifications		I. Sfiligoi
	  Need number of events in logger.mc_logger table
 	  Igor wrote new table so that we can make MC DST's from 
	    more than a single MC run

	Scripting for MC production	M. Moulson
	  Testing
	  Need to figure out why reconstrcuted file size not being logged
	  Number of events missing from logger.mc_logger (see above)

	Bank-reduction code for DST's   M. Moulson
	  Done

	Streaming code for DST's	C. Bloise
	  MC-truth based event filter done

	Scripting for DST production	M. Moulson, C. Bloise
	  Not yet started 
	  My estimate: > 1 week
