1. there was a problem with the t0 offsets.  clearly saw a notch in the

	coarse wire spectra, but not in the wire map spectrum.

	difference is that coarse wire spectrum looks for shortest time

	thus depends on t0 offsets.  This problem was solved when

	t0 optimizations were performed (and are now in the db_89044_...

	database)



2. there is a problem with the kinematic correction on the right side spectrometer,

	but our database is for (e,e'p) so I do not expect that the kinematic

	correction would be right anyway.  We need an ESPACE expert

	to tell us how to set this up so we can double check, that if

	the kinematic correction is done right we do reproduce the same

	spectrum on both sides, and that it is not still some real efficiency

	problem.



3. spectra replayed from ESPACE all seem to agree between SL and SR as

	long as kinematic correction does not come into play



Figure 1 below shows the delta, kin-corr delta, and u1 coarse posn spectra

for first SL and then SR.  Clear difference is kin-corr delta in SR, all others

look the same.



Figure 2 shows u1_wir (wire map) and u1_coarse for first SL, then SR.  Both

look same and look OK after allowing for the wire gap problem that appears

in ntuple output from ESPACE (see Adaq entry 49064 in halog)

Still need to understand this ntuple output problem, not at all clear why it

would cause gaps in the spectrum.
