The Tau2 and Quark cameras contained the normal imaging LUTs which contain 256 colors or greyscale
and map that to the 8-bit AGC data from the cameras. The imaging palettes are shown below. The
palettes only affect the analog and BT.656 outputs of the Quark 1, Tau 2.3 and earlier releases. The
Quark 2 and Tau 2.4 releases and later have an option for color in the CMOS and LVDS 8-bit data.

Figure 28: Look-Up Table Options (Without Isotherms)
The Tau 2.4 and Quark 2.0 releases and later added a second set of palettes associated with isotherms.
The cameras detect and image the temperatures in a given scene. Within the camera, these temperatures
are mapped (as determined by the AGC algorithm selected) to a range of 0 to 255 values. When Isotherms
are enabled, the camera uses the first 128 values of the AGC data which is relative to the scene and the
upper 128 palette values are linearly mapped to absolute temperatures.
The first Isotherm temperatures are mapped to 128 to 175, the second Isotherm temperatures are mapped
to 176 to 223 and the third Isotherm temperatures are mapped to 224 to 255.
The two MidRangeIso LUTs scale 0 to 127 for the first half of the gray scale, then the first two Isotherm
values use 128 to 175 to map yellow and then the scale continues on in gray scale until reaching the max
value of 255.
