Dear Referee,

	I appreciate your comments on the manuscript "Anomalies in
simulations of nearest neighbor ballistic deposition".  Since the time
of the original submission of the manuscript, I have implemented the
identical computer code, using a second pseudo random number generator
(PRNG). I believe this should address some of your comments, and
provide strong evidence of coupling between the BD and PRNG
algorithms.

	Essentially, implementation with a second PRNG yields
statistically distinct results, both for the scaling exponents
themselves and for measured, average quantities.  In addition, the
reported systematic decrease was not observed for the implementation
with the second PRNG, but fluctuations, outside of statistical error,
were observed (for the identical system, run with the identical code).
Hence a different dynamics was observed for the implementation with a
second PRNG, showing the dynamics is not inherent to the BD model
itself. Note that the identical code was used for the BD simulations
with both PRNGs and also for the RD simulations (which agree with
theory out to the longest times simulated, for the PRNG which
produced anomalous results for BD).

	It is reasonable that BD is more sensitive to correlations in
PRNs than standard Monte Carlo (MC) algorithms. In standard MC,
comparison to the Boltzmann probability causes rejection of some
numbers in a PRN sequence.  In BD all the PRNs produced are used and
used in the order they are produced.  Note that is restricted models
of growth, where physical constraints cause rejection of PRNs, the
theoretically predicted scaling exponents are recovered with great
precision in numerical simulations.

	With respect to your contention that both the short time and
asymptotic time exponents would be affected by correlated noise, it
should be noted that the alleged anti-correlation results from a
coupling of BD to PRNG algorithm. One would expect that the effects
of coupling would take some time to accumulate. 

	The above points have been incorporated in the manuscript.  I
would very much appreciate if you would take the time to reevaluate
this manuscript, in light of the above issues.


Sincerely,
