There is no file .ies type the file name correctly!
Program ies2tab converts IES photometric data to a table to standard output,
 or to a line with summary data (including the cutoff category).
 EULumDat format works as well, conversion to IES one 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)
-f : assume the data giving the Full space angle of outcoming light
-h : Help
-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)
-r : output angles in Radians (to ease polar plots by gnuplot)
-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 0.00:1.00:-2.50:2.50 pole heights);
-z#: extinction of light in Zenith / 1 mag (default 0.30)
