As Fig. 7, but for stars with relatively large proper motions centred around (μαcosδ,μδ) = ( + 10, +40) mas/yr with a radius of 15 mas/yr. Top: in 2MAst HQb5 (maximum number of objects per 0.25 × 0.25 deg2 pixel is about 60), bottom: in UCAC4 HQ (maximum of about 30). The Magellanic Clouds (MCs) are marked. Zonal effects at the edges of photographic plates used for the proper motion determination are seen in both plots. Some UCAC4 artefacts are marked.
