max_vel_theta parameter?

edit

Hi everyone,

In the source code "trajectory_planner_ros.cpp" of base_local-planner, I didn't see it retrieve the value of the parameter max_vel_theta. (You can confirm it with following command)

grep -R 'param("max_vel_theta"' *    // I got a empty response

But in my test, the parameter value DID control the in_place rotational velocity when the robot start to move to a goal. Is there anybody can tell me how the parameter value work??

Thanks!
