Scientific paper

There is an error in equations (10) and (15), which relate the eccentricity to the orbital parameters. The equations should read as follows:Eo=1/2μv2∞=1/2me- 1rp,(10)ande=2(Eo+ΔEo)/ mrp+1,a=rp/1- e,(15)where the impactor mass m replaces the reduced mass μ. The error does not affect the final results in any significant way, as it is effectively absorbed in the nonlinear correction factor, CNL. With the correct expression for the eccentricity, CNL should be 1.4, instead of 2.
