Acceptance of ET44 in 1998.

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 %.

 More details one can also find in the acceptance description for 
 1997 and 1996 years.
