The TCARIOSAVI operator algorithm computes the TCARI/OSAVI Ratio from a given product.

The TCARIOSAVI results from the following equation:

TCARIOSAVI = (3 * ((RE1 - R) - 0.2 * (RE1 - G) * (RE1 / R))) / (1.16 * (N - R) / (N + R + 0.16))

, where:

The bands are:

- G is the Green band
- RE1 is the Red Edge 1 band
- R is the Red band
- N is the NIR band

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

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