The SR705 operator algorithm computes the Simple Ratio (705 and 750 nm) from a given product.

The SR705 results from the following equation:

SR705 = RE2 / RE1

, where:

The bands are:

- RE1 is the Red Edge 1 band
- RE2 is the Red Edge 2 band
- R is the Red band

Also the processor computes an additional flags band called 'sr705_flags' with the following bit coding:

Bit Position	Description
Bit 0	The computed value for SR705 is NAN or is Infinite
Bit 1	The computed value for SR705 is less than -1 (minus one)
Bit 2	The computed value for SR705 is greater than 1 (one)
