Additional file 1 of Recovery and validation of Mars ionospheric electron density profiles from Mariner 9

The 114 Mariner 9 electron density profiles accompany this article as supplemental information. Each profile is provided in an ASCII text file. A header in the file provides orbit number, date, latitude, longitude, solar zenith angle, radius of reference areoid at that latitude and longitude, radial distance to the maximum electron density in the profile, and the value of the maximum electron density. The body of the file consists of three columns: radial distance, altitude, and electron density. The file naming convention is “orbitXXX.txt” where “XXX” is the orbit number, which ranges from “001” to “450”. (ZIP 269 kb)
