Notes. 1σ errors in the last digit(s) shown in brackets (see text for a discussion of the temperature errors). Empty fields denote non-detections.

(a)

Core numbers are from Rathborne et al. (2009).

(b)

Cores also discussed by Frau et al. (2010, 2012a,b), but using core numbers from Rathborne et al. (2008) instead of Rathborne et al. (2009). The corresponding numbers are as follows (Frau numbers in brackets): 3(6), 5(8), 9(12), 11(14), 16(20), 29(33), 34(40), 39(47), 40(48), 46(56), 53(65), 60(74), 71(87), 87(102), and 96(109).

(c)

Extinction data from Lombardi et al. (2006) instead of Román-Zúñiga et al. (2010).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
