### Panel Types & Coefficients <a href="#panel-types-and-coefficients" id="panel-types-and-coefficients"></a>

Sentera has sold three reflectance panel models, with different coefficients for each band. Check the cover of your panel to verify which coefficients you should use. You can also consult the image on the inside of your panel to determine which version you have, and use the following values.
