Annual differences of observatory revised monthly means (black dots) compared to the SV predictions from CHAOS-5l (solid red line), those from CHAOS-4l (green dashed line) and for the DTU SV candidate for IGRF-12 (blue circle, shown in 2015.0). For selected observatories, with locations marked in red in Fig. 3, arranged by geographic latitude and with field components rotated to the geomagnetic dipole frame
