   or change Parameters:
name='continuous' value='True'> assume a row of luminaires spaced:  heights
name='scale' value='True'> include a scale on the right margin
rotate plot: degrees (clockwise as +)
luminaire at height of  m (set the lamp flux as  lm)
Image height (pixels - 1)
name='summary' value='True'> start with summary results
  name='sumExpl' value='True'> incl. explanation on pollution by rays between 90 and 105 degrees

illuminance scale

Values below the scale are illuminance / 1 lx. Default (unrealistic) “unit” case is for luminaire being point-like, just 1 m over the terrain and containing a lamp producing exactly 1 klm. A realistic height can be given as a parameter, then the lamp flux given in the photometric file is used, if not overriden by a parameter.

If a continuous row of luminaires is computed, the result is shown at the left side. At the right side, illuminance produced by a single luminaire remains. Default spacing of luminaires is five pole heights. White marks are spaced one pole height, marks on axes are five times denser (0.2 height). ' ?>
