Hello,
to a:
the i3 dll uses an AGC in byte range... this means your whole thermal image can have only < 255 different temperatures.
This is not a problem for any case, but See this image (scroll down to "Thermovision_17.jpg"):

the mapcal is the first step to deliver "clean" images (with AGC usable for Night vision).
but after it, you need to translate the "radiation raw" to a temperature.
the 2 point calibration is fast and easy, but not accurate.
the Planc calibration is the way how Flir convert on their cameras. My opinion... i trust flir and believe its a good way but i don't know how they calculate/aquire the values.
i guess with the right settings you can use the TE-Q1 for accurate temperature measurements.
to c:
not yet, only these 2 generics.
Also a good way, maybe a third option in the future is a lookup table. This means you collect the real temperature using a NTC or digital Thermometer and the raw from the camera. and this for each temperature step. with some interpolations between the steps and a calibration source like a Tec it should be possible to catch a "calibration table" by driving a sweep and use the generated table later to get the temperatures from the camera.
(the Multimeter "Owon Bt 35", connected via Bluetooth is usable as "Serial Sensor". Maybe a good way to capture the real temperature)
but there is a problem... the sensitivity of a pixel (gain) and the total value shift to all other pixels (offset) is shifting if the detector temperature rise or fall after the calibration.
Well for offset is no big deal, its done by a NUC. so you may only need a gain LUT.
You have 2 options:
1. fix the temperature of the detector using a Tec controller (in case of the TE or Seek, the whole camera, if you dont want to open)
2. you have to do a "characterization" of the detector. this means you collect the gain versus detector temperature. after this you have a "temperature compensated gain" and use this to get a raw radiation value after NUC.
sadly i have not enough time for my hobby...
1. A Flir PM 695 waiting for combination with a sony Camcorder (record images+videos to MemoryStick)
2. i want to build my own tec controller (for core stabilization and as calibration target)
3. My TE-Q1 has a sutter from a old VCR camera and a big lens but need more modifications to be usable
and some other... and this is only the hardware stuff.
best wishes
