Calculate the ambient temperature ($T_a$)
The ambient temperature is used when calculating temperature of each pixel, and is also a
useful value by itself. It is calculated once per frame, and is used when constructing
CommonIrData. It is documented in sections 11.1.2 and 11.2.2.3 in both datasheets.
$$ T_a = \frac{\frac{V_{PTAT_{art}}}{1 + K_{V_{PTAT}} * \Delta V} - V_{PTAT_{25}}}{K_{T_{PTAT}}} + 25 $$
$K_{V_{PTAT}}$, $K_{T_{PTAT}}$, and
$V_{PTAT_{25}}$, are taken from calibration, while
$V_{PTAT_{art}}$ (v_ptat_art) and $\Delta V$ (delta_v) are the results of
v_ptat_art and delta_v respectively.
