Grid computation and details are explained in Gavazzi et al., 2019 [1] and exploited in Bertrand et al., [2].<br> This file contains non-null grid elements. PARAMETERS<br> Format : ASCII<br> Number of elements : 86902<br> Grid cell size : 125 m FIELDS<br> - LON : grid cell WGS84 longitude (°East);<br> - LAT : grid cell WGS84 latitude (°North );<br> - ALT : grid cell altitude amsl (m) - this grid was computed at a constant altitude of 1400 m above mean sea level;<br> - TMI : total magnetic intensity anomaly (nT);<br> - RTP : (double) reduction to the pole of the TMI (nT) - mean regional field direction Inclination=1.60°, Declination=64.14°;<br> - DV : vertical derivative of the RTP at order 0.5 (nT/m);<br> - DH : horizontal derivative of the RTP at order 1 (nT/m); [1] Gavazzi, B., Bertrand, L., Munschy, M., Mercier de Lépinay, J., Diraison, M. & Géraud, Y.
