Program ies2tab (v1.41) converts IES photometry to a table to standard output,
 or to a line with summary data (including the cutoff category).
 It can produce an illuminance plot too.
 EULumDat format works as well, conversion to IES and vice versa is possible.

 Its parameters are:
-a#: Albedo of the ground (default 0.10)
-c : write heading of Columns (just for an -l option)
-dp : compute sky luminance increment in distance instead of the overall one
      (valid for the -l option); -di or -la30 are synonyma
-e[{i|m}[<name]] : EuLumDat format
   -e as an input;
   -ei            makes an almost-ies file too (default name *.ies)
               (almost: just due to letting >132 characters on a line)
   -em as an output (default name *.ldt)
   -ea          try EuSym=0 in that :-( format...
-f : assume the data giving the Full space angle of outcoming light
-fs: for fully-shielded fixtures and one-line output: max. intensities
      instead of emissions over 90 degrees
-h : Help
-h#[:#] assume this height / m instead of 1 and take lamp flux from file
    [:# force this lamp flux / lm instead of that in the file]
   - an option affecting just the -u and -n outputs
-i#: Indicatrix type (default 0, P.Cinzano (2000), 4..6 CIE types also possible)
-ic: Include Comment lines in the output table
-l : one Line output only
-la# : limiting angular height for computing the increment of sky luminance
       in distance, default 30 (degrees);
       this increment is then given for the -l option
-m : compute candela multiplier (if it is erroneously set to 1)
-mi : output max. intensities at 65, 70 and absolutely
-r : output angles in Radians (to ease polar plots by gnuplot)
-rv# : rotation # degrees around vertical axis (for computing rectangle illum.)
-s[#:[<name>]] : write filenames of <= cutoff categories to <name>
    default limit is 1 (0=FCO, 1=FS, 2=CIE-CO, 4=IES-CO, 5=CIE-SCO...),
    default name is sc.lis
-t[y]# : tilt of the luminaire / 1 degree, around y-axis (perp. to the road)
 tx# : its tilt around x-axis (may be OK for long sloped roads)
-u[#:#:#:#] : compute illumination of a rectangle of
    xmin:xmax:ymin:ymax luminaire heights, zero being below the luminaire
    x axis going to 0 degrees and y to 90 degrees
    (default -0.50:1.50:-3.00:3.00 pole heights);
-z#: extinction of light in Zenith / 1 mag (default 0.30)

 a separate set of parameters serves for producing illuminance plots:
 -n[file_name] make a log-coded illuminance image <file_name>.ppm,
     default <file name> is the same as the input file name
 -cm# number of pixels per 0.2 pole height (6 is both default and maximum)
 -cs add a scale at its right margin (-cn to get rid of it)
 -co assume a continuous row of luminaires (-c- to get rid of it)
 -rh#    spaced # heights (default 4)
