base notes	It seems from Becker'19 chart that 'MN 2' has been subdivided into two short (equal) MN 1 and MN 2; whereas earlier, MN1 had extended down to also include A. pristina (base of Frasnian). Therefore, MN 1 and MN 2 are upper/lower of former MN 2 of GTS 2004 reference-spline scale here.				comp notes
