As anticipated on 12 February, for Swarm Alpha and Charlie only, the VFM (Vector Field Magnetometer) scaling that changes with time, i.e., s_t, needs to be slightly adjusted starting from 1 January 2018 onward.

To introduce this improvement in the Swarm Alpha and Charlie Magnetic field data, a regeneration of L1B MAGNET products has been performed for data from 1 January 2018 to 6 February 2020.

Please note that a File Counter increase has been introduced for all the L1B products regenerated.
