diagrams for each of the four categories of transient candidates (see text) that fall in the transient region and (delimited by the long-dashed lines) from their R_EROS light curves. The short-dashed diagonal line locates the diagonal . Top panel: transient candidates with bursts or outbursts (black squares for type Ba, blue diamonds for type Bb, and red circles for type Bc candidates). Second panel from top: transient candidates with trends (type T, black squares) and unclassified candidates (type X, gray dots). Bottom panel: transient candidates with pulsating-like features in their light curves (black squares for type Pa, blue diamonds for type Pb, and red circles for type Pc candidates). The correspondence between the labels in the figure and the EROS source ids is given in Table 1.
