Re Re: [Radiance-general] mgfilt, degree Kelvin into spectral data

[Christian Fusenig]

Thanks for your answer Greg,
---------------------
The normalization of the spectral power distribution is unimportant,  
but I believe mgfilt outputs something that sums to 1.0 when  
integrated with the photopic curve.  Whatever it comes out to, the  
actual value is normalized by the reflectance or emission it's  
applied to.  Since you aren't applying it to anything, it doesn't  
matter.
----------------------
The problem is, i am applying the spectrum of this lamp to a color filter spectrum.
The spectral data of this filter is normalized to 1 or 100%. There are values from 0,0000 up to 1.
If i multiply these two spectra as shown in "Rendering with Radiance" p.435, i think the data should be normalized
to the same standard, or am i wrong?
My output is a combined spectrum and then i convert it back to CIExy values, then with xyz_rgb.cal to RGB.
Thats why i want to know how mgfilt works and what it is capable of. Is there any man page?
Regards,

Christian
