 - `thermal` specifies a model for heat transfer across the bubble interface by an integer from 1 through 3.
 `thermal = 1`, `2`, and `3` correspond to no heat transfer (adiabatic gas compression), isothermal heat transfer, and heat transfer with a constant heat transfer coefficient based on [Preston et al., 2007](references.md), respectively.
 
-- `polydisperse` activates polydispersity in the bubble model through a probability density function (PDF) of the equilibrium bubble radius.
+- `polydisperse` activates polydispersity in the bubble model through a probability density function (PDF) of the equilibrium bubble radius. Simpson's rule is used for integrating the log-normal PDF of equilibrium bubble radius for polydisperse populations.
 
 - `R0ref` specifies the reference bubble radius.
 
 - `nb` specifies the number of discrete bins that define the probability density function (PDF) of the equilibrium bubble radius.
 
-- `R0_type` specifies the quadrature rule for integrating the log-normal PDF of equilibrium bubble radius for polydisperse populations.
-`R0_type = 1` corresponds to Simpson's rule.
-
 - `poly_sigma` specifies the standard deviation of the log-normal PDF of equilibrium bubble radius for polydisperse populations.
 
 - `Ca`, `Web`, and `Re_inv` respectively specify the Cavitation number, Weber number, and the inverse Reynolds number that characterize the offset of the gas pressure from the vapor pressure, surface tension, and liquid viscosity when the polytropic gas compression model is used.
