The Mercator family tempers out Mercator's comma, [-84 53⟩, and hence the fifths form a closed 53-note circle of fifths, identical to 53edo. While the tuning of the fifth will be that of 53edo, 0.069 cents flat, the tuning of the larger primes is not so constrained, and the point of these temperaments is to improve on it.

Cartography temperament

In terms of the normal comma list, Cartography is characterized by the addition of the schisma, 32805/32768, to Mercator's comma, which completely reduces all commas in the Schismic-Mercator equivalence continuum to the unison, and thus, the 5-limit is exactly the same as the 5-limit of 53edo. Cartography can also be characterized as the 53&159 temperament, with 212edo being a possible tuning. It should be noted that the 7-limit is somewhat independent for this temperament and is only really fully nailed down in one way or another by extending to the 11-limit.

Undecimal Cartography

Undecimal Cartography nails down the 7-limit by adding the symbiotic comma to the list of tempered commas.

13-limit

13-limit Cartography adds the island comma to the list of tempered commas, and while this extension is connected to the 5-limit, it is independent of the 11-limit and 7-limit, so it can just as easily be added by itself to make a no-sevens no-elevens version of Cartography.

Pentacontatritonic

This temperament differs from Cartography in that it uses a different 11-limit extension to nail down the 7-limit- specifically, the swetisma.

13-limit Pentacontatritonic adds the schismina to the list of commas being tempered out- this extension is connected to the 7-limit.
