The BAI operator algorithm computes the Burned Area Index from a given product.

The BAI results from the following equation:

BAI = 1.0 / (pow((0.1 - R) , 2.0) + pow((0.06 - N) , 2.0))

, where:

The bands are:

- R is the Red band
- N is the NIR band

Also the processor computes an additional flags band called 'bai_flags' with the following bit coding:

Bit Position	Description
Bit 0	The computed value for BAI is NAN or is Infinite
Bit 1	The computed value for BAI is less than -1 (minus one)
Bit 2	The computed value for BAI is greater than 1 (one)
