Properties of class 5 (group 5), which contains 9144 stars (N). The panels in the uppermost diagonal contain histograms for Teff, [M/H] and [α/M], from left to right, respectively. In these plots vertical black dashed lines show the median value and the limits enclosing 68.3 percent of the data points around the median value. The green histograms correspond to the objects in class 5 and the grey histogram shows the distribution of the whole group 5. As indicated by labels in the axes, the other three panels show 2D histograms for Teff − [M∕H], Teff − [α∕M] and [α∕M] −[M∕H]. From outside to inside the contours enclose 68.3, 45, 30, and 15 per cent of the objects in the class.
