UVOT count rate images of NGC 1543 by filter (see composite images in Fig. 7 for reference). Following Hoversten et al. (2011), non-white areas have a count rate higher than 0.028 counts s^-1 pixel^-1, which indicates that coincidence loss effects are larger than 1% in images binned 2 × 2. U, B, V images appear affected by coincidence loss effects, although only at a few percent level. Conversely, NUV images are not affected (see text).
