Mechanical heating rates for different densities and FUV luminosities for models whose metallicity is Z = Z.

106 105 3.4 × 10-17 0.3 >1000

Notes. These models span the full density and UV ranges we have explored. Almost the full range of mechanical heating rates are also covered, from quiescent discs (first row) to highly turbulent starbursts (last row).
