From page 367... ... MARINER IV MEASUREMENTS NEAR MARS -- INITIAL RESULTS The resolution of the telemetered magnetic data was 0.35 gamma per axis (1 gamma = 10-5 gauss) , a limit imposed by the uncertainty inherent in converting the magnetometer output analog signals to digital numbers be- fore transmission to Earth.

From page 368... ... 360 affect our estimate of the Martian di- pole moment, since a moment large enough to cause a significant effect dur- ing this interval would have caused detectable effects before occultation. Satellite and space probe measure- ments made near the earth must be scaled in order to make them applica- ble to a planet having a different dipole moment. Read the entire page →
