return ''' # Single photometric illuminance measurement. Light should be assumed to be
# measured along the sensor's x-axis (the area of detection is the y-z plane).
# The illuminance should have a 0 or positive value and be received with
# the sensor's +X axis pointing toward the light source.
# Photometric illuminance is the measure of the human eye's sensitivity of the
# intensity of light encountering or passing through a surface.
# All other Photometric and Radiometric measurements should
# not use this message.
# This message cannot represent:
# Luminous intensity (candela/light source output)
# Luminance (nits/light output per area)
# Irradiance (watt/area), etc.
Header header # timestamp is the time the illuminance was measured
# frame_id is the location and direction of the reading
float64 illuminance # Measurement of the Photometric Illuminance in Lux.
float64 variance # 0 is interpreted as variance unknown
