	Proxy data used for the reconstructions:
		proxy_ama_2.0.0_HR-0.67_infilled_DINEOF_1850-2000_PAGES-crit-regional+FDR.txt: high-resolution (annual and higher) and infilled (calibration period) subset of the PAGES2k v2.0.0 proxy data used for all methods (210 records), see Methods section and PAGES2k Consortium, 2017, Scientific Data, doi: 10.1038/sdata.2017.88. Data are tab separated, the first row is the "paleoData_TSid" to identify each record in the metadata file. First column is year CE.
		metadata_2.0.0_calib-selection_1881_1916_1995_0.67_infilled_DINEOF_PAGES-crit-regional+FDR.txt: According metadatam tab separated. Contains a selection of PAGES2k v.2.0.0 database fields in each row: dataSetName, geo_latitude, geo_longitude, archiveType, resMed (Median resolution in years), paleoData_TSid (the column header in the data files).
