A 13-note hemiwuershmidt modmos

Hemiwuerschmidt (99&130) has a 7-limit Graham complexity of 16, so we
need to get up at least to the 19-not MOS before having complete tetrads
in a MOS. Here I give a 13-note modmos, found via more pen & paper
fiddling, which has three major tetrads and two minor tetrads, which
is not bad for 13 notes tempered in something more accurate than
miracle. It JI lattice terms, it has [-2,0,0], [0,0,0] and [1,1,0] for
major tetrads and [-1,0,0] and [0,1,0] for minor tetrads, so the
harmony links together nicely. In terms of hemiwuerschmidt generators
it is
0,2,5,7,9,10,11,14,16,19,21,25,30 which reduces mod 13 to a complete
set of residues. Here it is in the 229-et poptimal tuning:

In case someone is planning to throw a conniption about discussing
tuning on the tuning list, be it noted that this got posted here by
accident. I had intended to post it to tuning-math, where such
behavior is at least tolerated.
