+That is, the module takes the outer density and pressure of the BE sphere (rho(Rbe), P(Rbe)) and copies these values to the ambient object. There is a weight factor attached to rhoOut, however, that controls how light the ambient is compared to the sphere's outer most edge. This weight is easily modified in the problem.data file. The B-field and V-field are set next to their values in problem.data. These values are set to zero by default.
 
 
 === Units ===
--also add bit on the print statements in the standard out
+
+The 3 parameters the user sets in problem.data should be in units of: [central_rho]:= particles/cm^3^, [xi]:= unit-less, but should be chosen based on desired stability [wiki: u/BonnorEbert see], [clump_rad]:= cm. The scales should be chosen accordingly.
+
+=== Standard Out ===
+
+The BE module comes with a few lines of helpful information printed out at the beginning of astrobear's standard out. This includes the central density of the BE sphere in cgs, the crossing time of the sphere in computational units, the isothermal sound speed of the sphere (note, this will be different in the ambient if there is a temperature discontinuity across the sphere-ambient interface) in cgs, and whether or not the BE sphere should be stable if no perturbations are present.
