Fig. 15


Top: cut-out of the B11 V reference image corresponding to the field of view of the red EMCCD camera. Bottom: reference image from S13, giving the positions of the variables confirmed by B11 and the two new variables V57 and V58 (note that V58 is not the star that is located at the upper right edge of the circle, but a star that is too faint to be detected at the epoch of the reference image). North is up and east is to the right. The image size is 45 × 45 arcsec2. Notice the greatly improved resolution compared to the B11 finding chart. (Reproduction of Fig. 1 in S13.)
