base notes	Martinez et al. (2013, 2015) has set implied base of T. pertransiens (hence Chron M14r.3) as 86% up in B/V; (hence 85% of a cycle above Chron M14r.3). However, to fit GTS2020 Spline-Mag, then M14r.1 used here plus 75% of the cycle.				comp notes	Basal cycle = B/V Martinez_cycle. The equation used to calculate the age of the event is 0.1 M14r + 0.75 x .405 - this is too much of a hybrid calculation for my system. I could simplify it to an offset from base T. pert TAZ, but it is not clear why they used .75 rather than .86 of a cycle offset from base T. pertransiens TAZ. So I have simply calculated the position within M15n from the given age.
