McGarrah-Reed House, Arkansas - AR059 Additional Site Information K. Thomson D.W. Stahle Purpose of Collection: Climatology Measurement type: Total ring width 1st Detrending method: Negative exponential; if cannot be fitted, then fit a regression line of any slope. 2nd Detrending method: If exp. is fitted, then a cubic spline with half power cutoff equal to series length is fitted; if the exp. cannot be fitted and a regression line is, then a spline with half power cutoff equal to 67% of the series length is fitted; In no case is a spline with half power cutoff less than 100 years fitted. Location of core material: Stored in U. of Arkansas Tree-Ring Lab; Part of the U. of Arkansas Museum collections, Accession No. 83-159. Publication citation: Thomson, Kerr J. 1990.
