Corrections for the inefficient hodoscope slats

Some slats of H2 and H3 have had low signal because of bad coupling between the light guide and the phototube. For these slats the separation between the pedestal and the 1 MIP peak was so small that they might only ``fire'' part of the time. A Monte Carlo inefficiency correction procedure was used to correct for that. It was based on efficiency monitoring carried out off-line run-by-run. The efficiency of suspect channels in a particular run was calculated by comparison of its bin content with two neighboring ones. The number of tracks in a run would be recorded. The overall efficiency of a channel throughout a series of runs used in the analysis would be calculated as a weighted average efficiency. The total loss of efficiency due to the slat malfunction was of the order of few percent. The same procedure corrected for the ``dead'' slats.
