Good day I recently changed my Evalscript for downloading S1 GRD images and since the change my PU usage has gone up exponentially. See below the Evalscript before the change:

evalscript = """

//VERSION=3



function setup() {

  return {

    input: [

      {

        bands: ["VV","VH"],                  

      }

    ],

    output: [

      {

        id: "default",

        bands: 2,

        sampleType: "FLOAT32",        

        noDataValue: 0,

      },    

    ],

    mosaicking: "SIMPLE",

  };

}





function evaluatePixel(samples) {

    // Your javascript code here

    return {

      default:[samples.VV, samples.VH],

    };

  }



function updateOutputMetadata(scenes, inputMetadata, outputMetadata) {

  // Write your code here

}

function preProcessScenes(collections) {

  return collections;

}

"""

See below the changed Evalscript which increased the PU usage, on the documentation it says dataMask does not count as a band.

evalscript = """

//VERSION=3



function setup() {

    return {

        input: [

        {

            bands: ["VV","VH","dataMask"],

        }

        ],

        output: [

        {

            id: "default",

            bands: 2,

            sampleType: "FLOAT32",        

            noDataValue: 0,

        },    

        ],

        mosaicking: "ORBIT",

    };

    }



     function evaluatePixel(samples) {

        // initial variables as the noDataValue

        let mosaic_vv = 0;

        let mosaic_vh = 0;

        

        // initial self-defined dataMask as 0 which means no data

        let mosaic_dataMask = 0;



        // for each pixel we check all available acquisitions and select the one having data

        for (let i = 0; i < samples.length; i++) {

          if (samples[i].dataMask === 1) {

            mosaic_vv = samples[i].VV;

            mosaic_vh = samples[i].VH;

            mosaic_dataMask = 1;

          }

        }

        return {

        default:[mosaic_vv, mosaic_vh, mosaic_dataMask],

        };

    }
