if the selected mosaic have 0 images, then the vrt cannot be build. more importantly the .vrt will have no spatial footprint so even if I catch the error, the window reading will fail eventually.

raise an error, users should not try to see too far back in the past
create a dark image, spatialy located on the tile to prevent the script from failing
