VESPA mercury_mag_boundaries sample

This dataset is based on the original MESSENGER mission magnetometer and coordinate data as made available at PDS PPI. It introduces a number of improvements upon the original [1 sec temporal resolution]: Magnetometer calibration signals have been removed. Coordinates and magnetic field measurements have been merged together. Additional fields, such as model dipole magnetic field and planetary position in a heliocentric coordinate system have been added. The dataset has been split up into files by orbit numbers, with each file centered on the periapsis. Data for a number of partially recorded orbits has been removed.
