SYN VG1 corresponds to the daily synthesis, i.e. the single "best" value for top of canopy reflectance at the four selected channels, based on those giving the maximum value of a vegetation index.
Note: the "max NDVI" composite method could be replaced by a different one, following the recommendations raised in coming evolutions.
