Swarm vector magnetic field maps
================================

.. contents:: Table of contents

Vector magnetic field maps in quasi-dipole latitude vs magnetic local time coordinates derived from the Swarm constellation data acquired at 1 second cadence from 1 January 2014 to 31 December 2020. The output consists in nine .jpg or .png files mapping the three components of the vector magnetic field in polar and equatorial projections (3 images for the three components) for each of the 3 satellites of the Swarm constellation. Each map has a size of about 300 kB.
