 You can create an original mask to specify the data collection range for the heatmap explained in step 7 of the "How to Use" section.
 
-1. Change the `MASK_NAME` parameter in `config/common_param.yaml` from its default value of `default` to any name you prefer. Here, the name 'original' is used.

 2. Modify parameters such as VEL_ACC_THRESHOLD, VEL_STEER_THRESHOLD, and VEL_ABS_STEER_RATE_THRESHOLD to determine the desired amount of data for each cell in the speed-acceleration heatmap, speed-steering angle heatmap, and speed-steer rate heatmap.
