I am using a thermopile whose dataset is available around 38301 values. This is purely mathematical query. Need to find two unknowns in below equation:

Vtp = K( Tobj^(4-n) - Ta^(4-n) )

Company says K & n are empirically determined value & this they wont tell.
Vtp is in volts
Tobj & Ta are in kelvins

Here is 38301 dataset: https://drive.google.com/file/d/1Kzok_MVeLRNiUz59HZl6xHrpkh5dg3mg/view?usp=sharing

Again this is purely mathematical query, just to see if it can be find out.

From these 38301 dataset values, we need to find best fit values of K & n, so that in final calculations when Tobj is to be calculated from known values of Vtp,Ta,K & n, this has minimum error.
