Raw Message Definition
# Sensor data pertaining to the Wiimote infrared camera.
# This message contains data for one of the four infrared
# light sources that the camera detects.
#
# Each light is specified with a 2D position and
# a 'source magnitude' (ir_size). If the x dimension
# is set to INVALID_FLOAT, then no light was detected for
# the respective light. The Wiimote handles up to
# four light sources, and the wiimote_node.py software
# is written to that limit as well.
#
# I am unsure what the 'ir_size' values represent.
# They are described as 'source magnitude' in some places. I
# *assume* this is signal amplitude, but it's unclear.
# Note that current lowest level cwiid driver does not
# seem to pass the ir_size value to the cwiid Wiimote.c.
# For now this size will therefore be set INVALID
