Morphological measurements of common voles, Microtus arvalis

Morphological coordinates collected from 2D images of common vole skulls. Raw cartesian coordinates in pixels are given in columns Rawx1, Rawy1 through to Rawx30, Rawy30. Columns with respective names starting with Ali are Proscrustes coordinates; the shape variables after the Procrustes superimposition. Samples are labelled with the population code and number from the individual voucher.

本数据集包含从普通田鼠头骨二维图像中采集的形态学坐标。以像素为单位的原始笛卡尔坐标存储于Rawx1、Rawy1至Rawx30、Rawy30列中。名称以Ali为前缀的列为普洛克拉斯提斯坐标（Proscrustes coordinates），即经过普洛克拉斯提斯叠加（Procrustes superimposition）处理后的形状变量。样本通过种群编码与个体凭证标本的编号进行标注。
