Data for: EvoDevo in owl ear asymmetry – the little owl (Athene noctua)

Sheet 1: Application of Kagurasho’s method (Kagurasho, M., Yamada, S., Uwabe, C., Kose, K., Takakuwa, T., 2012. Movement of the external ear in human embryo. Head Face Med. 8, 2.) to the little owl data in a lateral view. The center of the anatomical coordinate system was defined by the condylus occipitalis. The Y-axis crossed the pituitary gland. The X-axis was arranged orthogonally.

Sheet 2: Application of Kagurasho’s method (Kagurasho, M., Yamada, S., Uwabe, C., Kose, K., Takakuwa, T., 2012. Movement of the external ear in human embryo. Head Face Med. 8, 2.) to the little owl data in a frontal view. The center of the anatomical coordinate system was defined by the condylus occipitalis. The Y-axis crossed the pituitary gland. The X-axis was arranged orthogonally.

Sheet 3: Maximum and orthogonal diameters of the ear openings of little owls. The area and eccentricity were calculated from these diameters.

Sheet 1: 将Kagurasho法应用于侧视视角下的小鸮数据集，该方法源自Kagurasho M、Yamada S、Uwabe C、Kose K、Takakuwa T于2012年发表于《Head Face Med》第8卷第2期的研究论文《人类胚胎外耳的运动》。本研究以枕骨髁（condylus occipitalis）作为解剖坐标系（anatomical coordinate system）的原点，Y轴穿过垂体（pituitary gland），X轴与Y轴正交设置。
Sheet 2: 将Kagurasho法应用于正视视角下的小鸮数据集，坐标系设置与Sheet 1一致，即以枕骨髁定义解剖坐标系的原点，Y轴穿过垂体，X轴正交排布。
Sheet 3: 统计小鸮耳孔的最大直径与正交直径，并基于上述直径参数计算耳孔的面积与偏心率。
