PVO VENUS ONMS BROWSE SUPRTHRML ION MAX COUNT RATE 12S V1.0

This data set represents the maximum count rate per second in a 12 second period beginning with the time of the first data point for a given mass number. Although species other than O+ cannot be reduced to to a flux and direction it is possible to estimate the approximate flux from the maximum count rate per second occurring within one spin period (about 12 seconds). The maximum count rate can be approximately converted to a flux using: [4.E7 (particles/cm**2/sec)]/[1.E4 (counts/sec)]. This sensitivity is for O+. At higher mass numbers the sensitivity is less, being about a factor of 2.5 lower for Ar+.
