How to use the calculator with multiple bands in MapInfo Pro Advanced 16.0

UPDATED: April 28, 2017


User running MapInfo Pro Advanced 16.0 and needs to do math operations on raster data stores in multiple bands in a single .mrr format file.
Using example below, how can this user set  Input_1 as katrisk_59_yll_51 band 2 and Input_2 as katrisk_59_yll_51 band 3 ?

When you enter an expression for a multi-band dataset you can reference the individual band indexes in the dataset using square bracket [] notation in the expression. Band indexes are zero based so the first band in the file is index = 0, the second band is index = 1 etc

So if you wanted to divide the 3rd band by the 4th band in a 7 band file you would create an expression as follows:

Input_1[2] / Input_1[3]

In the customers case the expression would look like this for bands 2 & 3:

Input_1[1] / Input_2[2]

where
Input_1 = katrisk_59_yll_51
Input_2 = katrisk_59_yll_51
