Examples of the fitted distributions. The observed phase-space density as a function of energy is plotted with black dots, the fitted distribution for the warm population is plotted with blue, and the hot population with red. The black curves are the sum of the warm and hot population distributions and the constant background term. Upper panels: examples of distributions when the fitted parameters were accepted. Lower panels: indicate when the fitted parameters were rejected from the study. The χ² values for the upper panels from left to right are 68.4, 21.6, and 8.4.
