describing layers in costmap .yaml files

edit

so, we have 3 .yaml files:

1) common_costmap.yaml

2) global_costmap.yaml

3) local_costmap.yaml

For example, let global_costmap has these layers:

  plugins:
      - {name: static,            type: "costmap_2d::StaticLayer"}
      - {name: inflation,         type: "costmap_2d::InflationLayer"}
      - {name: sonar,             type: "range_sensor_layer::RangeSensorLayer"}

where am i supposed to describe layers params, in global_costmap or common costmap or in both?

i mean these lines:

static:
   map_topic: /map
   subscribe_to_updates: true

inflation:
   inflation_radius: 0.4

sonar:
   frame: range_sensor_frame
   topics: ["/sensor_us", "/sensor_ir"]
   no_readings_timeout: 2.0
   clear_on_max_reading: false
