tokens: The meteoroid model shall be selected according to the mission altitude as follows : 1 . For the analysis of meteoroid fluxes in Earth altitudes below 36 786,0 km , use either the meteoroid part of the MASTER-2005 model specified in clause 10.2.3 or the model specified in clause 10.2.4 . NOTE The meteoroid model in 10.2.3 is defined for particle masses from 10 - 12 g to 100 g . The meteoroid model defined in 10.2.4 is defined for particle masses from 10 - 18 g to 100 g . 2 . For the analysis of meteoroid fluxes in orbits not covered by 10.2.2.2a.1 and between the mean Venus and Mars heliocentric orbits , use the model specified in clause 10.2.4 . NOTE 1 This includes the moon distance and the Lagrange points of the Sun - Earth system . NOTE 2 Contributions from the meteoroid stream model specified in clause 10.2.4.5 can be neglected for orbits between Venus and Mars and not covered by 10.2.2.2a.1 . NOTE 3 For interplanetary orbits outside of the range defined in 10.2.2.2a.1 and 10.2.2.2a.2 no reference model is specified . Available interplanetary meteoroid flux models are given in Annex J.2.1.5 .
