+- Positivity limiting for conservative (`positivity_variables_cons`) and nonlinear variables (`positivity_variables_nonlinear`)
 - One-sided limiting for specific and mathematical entropy (`spec_entropy`, `math_entropy`)
 
 Conservative variables to be limited are passed as a vector of strings, e.g. `local_minmax_variables_cons = ["rho"]`
-and `positivity_variables_cons = ["rho"]`. For non-linear variables the specific functions are

 passed in a vector, e.g. `positivity_variables_nonlinear = [pressure]`.
 
 The bounds can be calculated using the `bar_states` or the low-order FV solution. The positivity
 limiter uses `positivity_correction_factor` such that `u^new >= positivity_correction_factor * u^FV`.
