Appendix A:

Temperature contours at AV = 20 for different values of mechanical heating. As mechanical heating is increased from 10-24 to 10-16, the temperatures increase from left to right in the grid as function of increasing mechanical heating. The temperatures to the left of the highest temperature contour line are higher than the temperature of the contour curve itself, which are usually larger than 10 000 K. The models in these regions are not very accurate since cooling effects for temperature larger than 10 000 K are not included properly, so we do not plot the corresponding contours.
