Values below the scale are illuminance / 1 lx. This is for (unrealistic) “unit” case that luminaires would have lamps producing 1 klm each and would be 1 m over the terrain. A more realistic case would be lamps producing 10 klm each and being 10 m over the terrain: then the illuminances would be just 10× less.
Each plot consists from two parts. At its right side, illuminance produced by a single luminaire is shown. This is right from the vertical axis corresponding to the 0-180 azimuth axis (0 is upwards). To the left from this axis, a result for a a continuous row of luminaires positioned five pole heights apart is shown. The horizontal axis is 90-270 one, just below the row of luminaires. In the photometric files, however, the azimuths have various origins (0, 90, 180). White dots in the plots mark one column height.
