Ratio of virial parameters from the simulations of Federrath & Klessen (2012, Federrath & Klessen 2013) for three different types of forcing. Each point corresponds to a Mach number, ℳ, and size L. Triangles (sol/comp) show the ratio between virial parameters for solenoidal (b ≃ 0.3) and compressive forcing (b ≃ 1) and circles (sol/mix) show the ratio between solenoidal and mixed forcing (b ≃ 0.4). The horizontal dashed lines give the expected value of th e ratios for a scaling in b⁻².
