Jeff Id has identified another intriguing mystery in the arduous problem of determining what Mann’s realdata was. Jeff observed that the version of the Luterbacher lutannt10 series in Mann’s infilled data version allproxy1209 was different than the version of lutannt10 in allproxyoriginal (Sep 5 version), illustrating this as below:
I also compared versions of this series in the 6 versions of Mann’s data archived over the past week (3 infilled versions, 2 distinct; 3 ‘original’ versions, 2 distinct). Two different versions of lutant10 occur in the 4 distinct versions. The version labelled “1209″ above occurs in the Sep 4 allproxy1209, Sep 5 allproxy1209 and WDCP proxy-infilled data sets, while the version labelled “original” occurs in the Sep 4 allproxyoriginal, the Sep 5 allproxyoriginal and the WDCP proxy-original data versions i.e. one version occurs in all infilled versions and an inconsistent version appears in all “original” versions.
The Luterbacher data is not itself archived and so there is, at present, no way to verify which is the “original” ‘original’ realdata. (I think that Hans Erren tried to obtain Luterbacher’s data a couple of years and was unsuccessful.)
Whatever the result, I guess that we’re going to see still one more version of either the infilled or original data and maybe even get the real realdata. At that point, we won’t just have the “original” data; we’ll have a Team of original data.
