| Remarks | Wagner VII variant, configuration 60-77-60-45-170 (using the Böhm notation, see Umbeziffern – The Wagner Transformation Method. Experimental, a Frančula XIII copycat, with bit less areal inflation. Briefly introduced in my blog. |
A Wanger IX variant, derived by Umbeziffern from the equatorial azimuthal equidistant projection, minimized distortion by application of the Airy-Kavrayskiy criterion. For more information, refer to my blogpost The Frančula Projections or Frančula’s original paper Die vorteilhaftesten Abbildungen in der Atlaskartographie (German). |

This pairing is among the list of recommended pairings – but why? The F13 Copycat deliberately approaches certain properties of the Frančula XIII (aspect ratio, length and curvature of the pole line) but the distribution of meridians and parallels is different. |
