base notes	CALIBRATION = 10.71% up Ae3 - Stimulograptus sedgwickii graptolite Zone				comp notes	CORRECTED? - the spreadsheet age was just given as an Ma age without being computed, I have instead used the calibration from the notes, which has shifted it slightly down (0.1 Ma). NB This change, and the others above fits the C13 curve better.
