Left: distribution of distance and proper motion. The major concentration of the UMa group is the UMa open cluster in the Big Dipper constellation at distances of about 25 pc. All known members and candidates (see references in the text) are included in the histogram (solid line; distances mostly from Montes et al. 2001 and van Leeuwen 2007). We add the distribution of the southern stars within 30 pc addressed in the present work (hatched; distances from van Leeuwen 2007). Right: image of the coronagraphic mask with the four coronagraphs (black filled circles) taken with the S27 camera. Each of the coronagraphs has an angular diameter of . We placed the star below the lower left (south-eastern) coronagraph, so that a field with a radius of ≈9′′ is completely covered outside the coronagraph (hatched circle). Incomplete coverage is achieved up to separations of ≈25′′ (arrow).
