V.Andreev, 21-December-1999
The 1998 H1 running period was devided on 4 samples. Each sample is
mainly different by X_off-position of beams in the interaction point.
The dependence X_off for the different H1 runs is shown on the next
picture. The acceptance curve for each sample was determinated
with the procedure described in H1 note #493 and then DB was updated
with the new set of LET1 banks :

The y-dependence of ET44 acceptance for different run periods is
shown on picture and the same distributions for the previous years
are also given for the comparision.
The systematic error of the acceptance determination for ET44 in 1998
is equal 4.5 %.
