Dear Stepan,

Thank you for your comments.
  1) I removed the reference to the cerenkov counters because we did not 
use them
  2) The text says that

    The final data set was grouped into four magnet cycles and each
    magnet cycle contained all possible configurations
    (c+t+,c+t−,c−t+,c−t− where c and t are the chi- cane and torus
    magnet polarities, respectively).

so when we removed the negative chicane data of cycle two, this refers 
to the c-t+ and c-t- parts of that cycle.
  3) Because they're not officially published yet.  We're fasttracking 
this paper in hopes that we can submit to PRL before Novosibirsk.
