Notes. Column 1 shows the parameter name. Columns 2 through 5 indicate the model names ‘R’ stands for resolution in number of cells per cloud radius, ‘AL’ and ‘TR’ stand for magnetic fields aligned with and transverse to the wind direction, respectively. Rows show the initial conditions of each parameter for each model. Quantities with overlines are volume-weighted averages, and quantities in between angle brackets are mass-weighted averages.
