# 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.
# "intensity" instead of "value").
string name
# The values array should be 1-1 with the elements of the associated
# PointCloud.
