It looks like in time calibration frames changes differences between subsequent calibration frames shows this nasty non uniform Seek sensor readings.
Attached those three choosen raw 16bit calibration frames 1,6,13 from one of router files provided before there-this one:
$ md5sum sts_router_frames.raw
52d19a3324a800fb15245f77542a6dec sts_router_frames.raw
However, this raw calibration data looks strange and histograms shows that senor values goes not high but down, but this is without correction from 207th column, while this image processing was done in
imagej2 on those 16bit raw PNGs attached, so now it's time to automate this calibration frames analysis process with OpenCV support and lets create 3D animation in OpenGL how this sensor values changes in time
BTW: Probably I've found where temperature is stored, but it will require setup with thermometers, while there were no information what ambient temperature was when this dongle was switched on, so will have to wait when this Sick Thermal thing will land in my PC Linux USB slot soon and next in
