This page makes available the proxy data files for the AMOC index as shown in Fig. 3 of:
Rahmstorf, S., J.E. Box, G. Feulner, M.E. Mann, A. Robinson, S. Rutherford, and E.J. Schaffernicht, 2015: Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation. Nature Climate change, DOI:10.1038/nclimate2554.
In each of the three files, the first data column is the year, the second is the data series, and the third is the 2-sigma uncertainty. (The instrumental data also shown in the panels are not included in the files; they are the HadCRUT4 data publically available here).
The Northern Hemisphere data and underlying explanations etc. are available from: http://www.meteo.psu.edu/holocene/public_html/supplements/MultiproxyMeans07/
The grid box data, explanations, etc. that go into the subpolar gyre series are available from: http://www.meteo.psu.edu/holocene/public_html/supplements/MultiproxySpatial09/

Needless to say, this does not change any of our conclusions. A formal correction was published on 3 September 2015.
