For M82, measurements have been made of the parameters that determine the physical properties of the Chevalier and Clegg model (CC85). In Strickland & Heckman (2009), fitting measurements of the hot x-ray gas within the starburst region to 1D models resulted in the following parameters:
- , with in the range 1.0 - 2.8
- , with in the range 0.3-1.0
Physical parameters of interest for the CC85 model with these parameters are shown in the plots below.
