Extended Data Fig. 2: All IFG data available as of Aug 1, 2019, covering sols 14-299.
From: Crustal and time-varying magnetic fields at the InSight landing site on Mars
Magnetic field components Bx, By, Bz in the local lander level (LL) frame from 11 December, 2019 until 29 September, 2019. Data gaps occur due to safing at times of APSS anomalies. The average field ± 1 std for the entire period is [BX, BY, BZ] = [-1353 ± 6, 1168 ± 5, -925 ± 6] nT. As nighttime data are less contaminated by external fields (ionospheric currents and the draped interplanetary magnetic field, IMF) we report the average field computed between local times of 8pm and 4am in the main paper. This is indistinguishable from that computed for all local times. The uncertainty in the crustal field is dominated by the uncertainty in the spacecraft field as described in the main text. Corrections for temperature and solar array currents are described in detail in the IFG Software Interface Specification (SIS) document available on the PDS (https://pds-ppi.igpp.ucla.edu/search/view/?f=yes&id=pds://PPI/insight-ifg-mars/document).
