    Further study of the decay $K sup +$$-> pi sup +$$nu$$nu$
    by V.V. Anisimovsky, A.V. Artamonov, B. Bassalleck, et al.



Dear Robert,

We would like to thank you and the referees for the helpful
comments. We have revised the paper to address all the points raised
as follows.

The title has been changed as suggested to " Improved measurement of
the K-> PI nu nubar branching ratio."

Referee A. We have expanded the introduction to describe specific
physics issues addressed by the measurement and related them to the
work being done in the B system. We have also added several new references
describing the relationship of the study to physics beyond the standard
model.

Referee B.  We have  reformulated the sections of the paper
that referee B discussed to better enable the reader to understand the
analysis methods used.  We have eliminated possibly confusing terms 
and provided clear explanations of the procedure. We eliminated possible 
confusion regarding the index "i" that referee B mentioned by explicitly 
defining its meaning.

As a result of the modifications mentioned above, we have also streamlined the 
description of the experiment to fit within the 4 page limit of PRL.  The figure
showing the detector schematic has  been eliminated. However, the essential 
details of the apparatus and the improvements associated with the E787 to 
E949 upgrade have been provided so that the general reader can understand
the technique.

We hope that the paper is now acceptable for publication in PRL.

Sincerely,

Douglas Bryman
