Figure 1. Map of the magnetic field of Mars at MGS mapping altitude of 400 (+/-30) km. The radial component of the magnetic field associated with crustal sources is illustrated using the color scale shown. Observations used for this map were obtained while the spacecraft was in the shadow of Mars during mapping cycles 1--12. We plot the median value of all observations for each 1 degree latitude by 1 degree longitude bin (60 by 60 km at the equator). Isomagnetic contours are drawn for B = +/- 10, 20, 50, 100, 200 nT.
