Empirical Analysis of Unaccelerated Velocity and Mass Distributions of Photographic Meteors
An empirical analysis was performed on data for 2000 sporadic meteors. A bimodal log-normal equation was found for unaccelerated velocity distribution, by empirical curve fitting to match observed velocity distributions for meteoroids within 10 ranges of mass with due regard to failure of observation of faint meteors. An exponent of -1.34 was confirmed in the equation for cumulative influx rate of meteoroids relative to mass. An exponent of -3.87 was established for meteoroid velocity relative to Earth's atmosphere as used in an earlier weighting factor for correction of biasing effects of velocity and mass. Earlier theoretical results were closely approximated.
