       -o [profile.icc]
              Create fast matrix/shaper profile [different filename to outfile.icc]

       -O "description"
              Fast ICC Profile Description string (Default "outfile")

       -u     Update previous calibration and (if -o used) ICC profile VideoLUTs

       -q [vlmh]
              Quality - Very Low, Low, Medium (def), High

       -p     Use telephoto mode (ie. for a projector) (if available)

       -t [temp]
              White Daylight locus target, optional target temperaturee in deg. K (deflt.)

       -T [temp]
              White Black Body locus target, optional target temperaturee in deg. K

       -w x,y Set the target white point as chromaticity coordinates

       -b bright
              Set the target white brightness in cd/m^2

       -g gamma
              Set the target response curve advertised gamma (Def.  2.4)  Use  "-gl"  for  L*a*b*
              curve  Use  "-gs"  for  sRGB  curve Use "-g709" for REC 709 curve (should use -a as
              well!)  Use "-g240" for SMPTE 240M curve (should use -a as well!)  Use "-G2.4  -f0"
              for BT.1886

       -G gamma
              Set the target response curve actual technical gamma

       -f [degree]
              Amount of black level accounted for with output offset (default all output offset)

       -a ambient
              Use viewing condition adjustment for ambient in Lux

       -k factor
              Amount to correct black hue, 0 = none, 1 = full, Default = Automatic

       -A rate
              Rate of blending from neutral to black point. Default 4.0

       -B blkbright
              Set the target black brightness in cd/m^2

       -e [n] Run n verify passes on final curves

       -z     Run only verify pass on installed calibration curves

       -P ho,vo,ss[,vs]
              Position  test  window  and  scale  it  ho,vi:  0.0 = left/top, 0.5 = center, 1.0 =
              right/bottom etc.  ss: 0.5 = half, 1.0 = normal, 2.0 = double etc.

       -F     Fill whole screen with black background

       -n     Don't set override redirect on test window

       -E     Encode the test values for video range 16..235/255

       -J     Run instrument calibration first (used rarely)

       -N     Disable initial calibration of instrument if possible
