The results presented in our report
(1) indicated that it was necessary to
consider dissociation during all collisions in
calculating the atmospheric loss from Mars
that results from sputtering. With the use of
the newly calculated cross sections presented
by Johnson and Liu in our model, we
find that Mars has lost about 1 bar of CO_2.
The revised cross sections reduce our sputtering
yields (Table 1), but do not bring our
results into agreement with Luhmann et al.
(2) and Jakosky et al. (3).
