Notes. Second column: average log g and, in parentheses, 1σ width of the distribution. Third column: average mass, error of the average and 1σ width of the distribution. N is the number of objects in the interval. BR is the number normalized with the cooling time through the interval and the luminosity to the 3/2 power.
