The DSWI5 operator algorithm computes the Disease-Water Stress Index 5 from a given product.

The DSWI5 results from the following equation:

DSWI5 = (N + G) / (S1 + R)

, where:

The bands are:

- G is the Green band
- R is the Red band
- N is the NIR band
- S1 is the SWIR 1 band

Also the processor computes an additional flags band called 'dswi5_flags' with the following bit coding:

Bit Position	Description
Bit 0	The computed value for DSWI5 is NAN or is Infinite
Bit 1	The computed value for DSWI5 is less than -1 (minus one)
Bit 2	The computed value for DSWI5 is greater than 1 (one)
