Hi Gerhard,
my CRT calibration is:
CRT/factory cal[0] = 0.085921
CRT/factory cal[1] = -0.003069
CRT/factory cal[2] = 0.023365
CRT/factory cal[3] = 0.002031
CRT/factory cal[4] = 0.055848
CRT/factory cal[5] = 0.000975
CRT/factory cal[6] = -0.001291
CRT/factory cal[7] = 0.001630
CRT/factory cal[8] = 0.158255
user cal flag = 0xd
CRT/factory cal[0] = 0.085171
CRT/factory cal[1] = -0.001949
CRT/factory cal[2] = 0.020907
CRT/factory cal[3] = -0.000824
CRT/factory cal[4] = 0.056916
CRT/factory cal[5] = 0.000868
CRT/factory cal[6] = -0.002336
CRT/factory cal[7] = 0.002253
CRT/factory cal[8] = 0.142963
CRT/factory flag = 0x45d31629 = Wed Feb 14 15:01:13 2007
Since the rationale for the matrices is the individual calibration of
each instrument, I guess that comparing just the matrixes from just two
instruments may not necessarily be too meaningful. I could also imagine
that a particular relation of some sort between the LCD and the CRT
matrix (for instance inv(CRT_matrix)*LCD_matrix ?) may be more invariant
between different instruments than the calibration matrices themselves.
If one were to assume that the only the LCD matrix was going to
be different between the instruments, then comparing something
like LCD A <-> LCD B * CRT A * inv(CRT B) may give an indication.
Cheers,
Graeme Gill.
