X-ray to bolometric flux distribution of the Hyades as a function of the BP − RP color. Blue, red, cyan, green, and orange dots indicate the values adopted from 2RXS, 2RXP, 1RXH, XMM, and CSC, respectively, while the triangles show the upper limits from 2RXP, 1RXH, and XMM pointings. The upper limits from 2RXS are shown as gray triangles in the background. In contrast to the detections in the core, the Hyades members in the tails are outlined in black. At the bottom we show the ranges of the spectral types as a guidance.
