Appendix 2 frames in normal orb webs

Raw data of tensile test of frame threads in normal orb webs with graphs regarding force-strain curve. In all graphs, X-axis is strain and Y-axis is force [mN]. First graph (above) is raw force-strain curve, second (middle) is thirty points' moving-averaged force-strain curve, and third (below) is extract of initial slope used for calculation of Young's modulus, if any. All sample names described in each sheet in this category are designated as OF (meaning orb web frame thread) with the number behind hyphen representing each sample (individual web). In this category, there is no replicates (a thread from one web).
