some ear derived 6-tone scales in 13 equal

While I was rummaging around to see if I could find the parts for
"With Eyes so Blue and Dreaming" in hopes of posting a bit on it, I
stumbled upon another piece that used the following ear derived 6-tone
scales in 13 equal.

0 4 6 7 9 11 13

0 2 3 7 9 10 13

0 4 6 7 12 15 19 (a peculiar, but nice, non-octave scale)

0 1 4 7 8 11 13

Here's the 6-tone scale in 11 equal from "Head of Flame" that I very
much like.

0 2 4 6 8 9 11

One of the interesting things about the 13 equal scales is that they
were all 100% ear derived (the 11 equal 222212 was not), and yet for
the most part they tend to resist easy theoretical interpretation.
