Hexagonal rosettes of growing dimension (gray scale hexagons) whose areas are ﹩3m_{h}( m_{h}-1) +1﹩, where m_h is the side of the rosette. Inset: The orientation of the hexagonal grid has been set in order to have ﹩\boldsymbol{e}_{1}\parallel \boldsymbol{f}_{1}﹩, where ﹩\boldsymbol{f}_{1}﹩ and ﹩\boldsymbol{f}_{2}﹩ are the hexagonal lattice vectors and ﹩\boldsymbol{e}_{1}﹩ and ﹩\boldsymbol{e}_{2}﹩ are the square lattice vectors. The horizontal dimension L, in hexagonal pixels, of the reported rosette is 3.
