NGC 4815 field: (left) DIB and A0 distance profiles. Stars identified by Friel et al. (2014) as cluster members correspond to blue, nonmembers to red markers. Right: 6283 (top) and 6614 (lower panel) Å DIB EW vs the estimated extinction A0. The black “0" sign indicates the unique star with a single DIB velocity, for all other targets the adjustment to the data requires two velocity components.
