Erratum: The Impact Ejecta Environment of near Earth Asteroids (Astrophysical Journal Letters (2016) 830 (L29) DOI: 10.3847/2041-8205/830/2/L29)

In the published Letter (Szalay and Horányi 2016a), there were two typos in Equations (1) and (2). These typos did not affect the conclusions as the equations were correct in the underlying analysis code. In reformulating the initial impact ejecta speed from Szalay and Horányi (2016b), Equation (1) inadvertently left off the square of the normalized velocity in the numerator of the exponential argument. The correct form is (Equation Presented) Equation (2) had an error in the Heaviside function, where the correct form is (Equation Presented) Both equations have been corrected in a subsequent review article (Equations (18) and (19) Szalay et al. 2018).
