Latitude-specific noise for the vector components B_r, B_ϕ, and B_θ for full-resolution low-cadence synoptic maps. The RMS (left) is measured in 10° increments from 20° to 90° in a quiet-Sun area. Solid lines show the result of the full-resolution synoptic maps at 3600 × 1440 px and the dashed lines for the small synoptic versions at 720 × 360 px. The three panels on the right show the respective region, starting north of the magnetic activity of the equatorial latitudes.
