Top left: extinction map obtained from VPHAS+ photometry in the distance range 2−4 kpc. The cross indicates the centre of the cluster. The dashed line shows the footprint of our BVI photometry. Bottom left: same extinction map. The black points are cluster stars selected from the (r − i,r) VPHAS+ CMD, with r< 16. The CCD gaps are visible as horizontal lines. Top right: extinction map from Schlegel (1998) for this field. Bottom right: same as bottom left, but with 2MASS main-sequence stars (J< 15).
