Distribution across the nebula of different physical values. In the left figure, the temperature (top right), density (top left), density of scalar linear momentum (bottom right), and density of kinetic energy (bottom left) are shown. In the right figure, the pressure (top left), Mach number (top right), scalar velocity (bottom left), and turbulence (bottom right) are shown. The axes are given in physical length units (centimetres). Note that 3.6×10¹⁶ cm subtends 1″.0 at the assumed distance of 2500 pc.
