I am using ENVI 5.4, specifically 'Data Stretch' tool in a bid to scale down my Landsat 8 OLI surface reflectance product values. I have populated the dialogue box (as below) and compared the histogram of the resultant raster with the original one.
However, there is anomaly noticed in its values (see histogram). I anticipate same histogram stretch however this is not the case.
Why there is such discrepancy in the results?
