    Hello.  I just posted a web page 
(http://pii3.brahms.bnl.gov/~hito/pp/UA1_Correction.html) correction 
factor of UA1 to BRAHMS correction factor.  I used the (almost) same 
technique as Claus.  (This is independent check.)  The effect of using 
average of h- and h+ instead of h- at forward rapidity is quite large 
(factor of 2.5 at pt of 4 Gev/c).   Also, an effect of colliding 
different species (PN, NN, PP) are ploted.  This effect seems to be 
small upto 3Gev/c.  After that, although the statistics is poor, there 
seemed to be difference.
