How do I integrate the xyzfix resulting matrix in the hcfr.c code? What are 
xmat and tmat in this file?

In what order do I have to call the .ti3 files in xyzfix?

BTW, as I can't make HCFR colorimeter work under linux, could send be a 
pre-compiled version of dispwin (I guess I only need this one) compiled 
with #define MEASURE_RAW, for windows (I'll make the calibration under 
this OS)?

Thanks,
