(a): LOMGRAV magnetic total field anomaly grid upward continued 3500 m above flight altitude, i.e. to an altitude of approximately 4100 m above geoid. (b): Difference (detrended by degree 1 polynomial) of LOMGRAV grid to EMAG2 grid shows generally good agreement between these grids; an area with systematic deviation is marked with a white ellipse in (a) and (b). (c): Levelled survey data as well as grid data along the traverse line indicated as black line in (b).
