Maps and contours showing the morphologies of the cores using two different definitions. The coloured maps show the ratio of thermal to infalling ram (kinetic) pressure, while the black solid contour defines the region where the gas density exceeds density thresholds of ρ_core = 10⁻¹⁰ g cm⁻³ for the first Larson core and ρ_core = 10⁻⁵ g cm⁻³ for the second Larson core. The panels are: (a) runID first core, (b) runAO first core, (c) runID second core, (d) runID second core. We note the difference in spatial scales between panels a and b.
