    Hi, Robert is the first name but I got by my middle, Joel.

    Thanks for the references, helpful but not exactly what I was hoping
    for. I was hoping for references to the actual tree ring data in
    which they show the ring data (pictures of rings, stats on widths,
    how the correlations among trees was done etcc..). The web site you
    refer to have no references included and although you/they elude to
    experts saying things they are still somewhat general in nature and
    don't show the sources. Are these reference the ones you are basing
    your opinion on? I'm not sure I could just accept this data without
    seeing the source. Not that I am doubting the particular tree ring
    data but surely Baille has published his data in journals, and it is
    the original journal articles that I am interested in getting my
    hands on. Thanks.
