The continuum corrected integrated intensities I^g,cc predicted with GASTRoNOoM are compared to the values I^D calculated with Eq. (8). Values for the exponents s_i,J in Eq. (8) are specified in the upper left corner. The full line represents equality of I^g,cc and I^D, the dotted lines show a factor 3 difference w.r.t. this relation. For all three distance values assumed in the model grid, the estimates are plotted in a different color: black for d = 300 pc, red for d = 1000 pc, and blue for d = 3000 pc. See Sect. 3.4 for further details.
