How to add the response function for each interval

[Lorayne Magalhães]

  Dear DART team,

I wanna simulate images of the ocean containing plastic polymers using the Sentinel-2 response function to develop an index. To do this, when I set the parameters in the editor, I add a certain number of intervals for each band. For example, for the blue band, I created 13 intervals (so that I can extract the spectral responses of the plastics in each of these intervals across the blue band). Therefore, I would like to know how to add the Sentinel-2 response function to each of the images generated for each of these 13 intervals.  Basically, I  would have liked to obtain the result of each individual small band multiplied by the corresponding response function. i.e. only : band[i] * response[i].  How is that possible?

Thanks for your attention.

Best wishes
