// Generated from the following "sensor_msgs/ChannelFloat32" msg definition:
//   # This message is used by the PointCloud message to hold optional data
//   # associated with each point in the cloud. The length of the values
//   # array should be the same as the length of the points array in the
//   # PointCloud, and each value should be associated with the corresponding
//   # point.
//   
//   # Channel names in existing practice include:
//   #   "u", "v" - row and column (respectively) in the left stereo image.
//   #              This is opposite to usual conventions but remains for
//   #              historical reasons. The newer PointCloud2 message has no
//   #              such problem.
//   #   "rgb" - For point clouds produced by color stereo cameras. uint8
//   #           (R,G,B) values packed into the least significant 24 bits,
//   #           in order.
//   #   "intensity" - laser or pixel intensity.
//   #   "distance"
//   
//   # The channel name should give semantics of the channel (e.g.
