     weighted by the coverage fraction of each pixel.
   * ``count(default_value=0)``: the sum of all pixel coverage fractions, including
     NODATA pixels, as they will be treated as having value 0 instead of being ignored.
-  * ``mean(min_coverage_frac=0.5)``: the mean value of pixels that intersect the
-    polygon. Only pixels with a coverage fraction of 50% or more will be considered in
-    the calculation and they will be weighted by the coverage fraction.

   * ``mean(coverage_weight=none)``: the mean value of pixels that intersect the polygon.
     All pixels with any coverage will be counted as having 100% coverage.
