Additional file 9 of Buoyancy and hydrostatic balance in a West Indian Ocean coelacanth Latimeria chalumnae

Additional file 9. Calculations of buoyancy, center of gravity andcenter of buoyancy for individual body segments (main body, fatty organ,pectoral fins, pelvic fins, dorsal fins, anal fin and 26 caudal fin segments)and combined. First tab contains combined measurements and all calculationsleading to Figs. 2d, 3e, f and 4d. Second tab contains calculations leading toTable 1. Subsequent tabs represent each of the 35 body segments. Each segment has three tabs representingcalculations in the transversal, coronal and sagittal planes except for thetail segments that only have a tab each for the transversal plane since tailbend was assumed not to contain a dorsoventral component (coronal plane) andhydrostatic balance in left/right axis (sagittal plane) is of less interestsince the specimen is not fixed in a posture with perfect bilateral symmetry.

附加文件9：针对单个身体节段（躯干、脂肪器官、胸鳍、腹鳍、背鳍、臀鳍及26个尾鳍节段）及其组合的浮力（buoyancy）、重心（center of gravity）与浮心（center of buoyancy）计算。首个工作表包含可生成图2d、3e、f及4d的组合测量数据与全部计算结果；第二个工作表包含可生成表1的计算内容。后续工作表分别对应全部35个身体节段，每个节段均设有三个工作表，分别对应横平面（transversal plane）、冠状平面（coronal plane）与矢状平面（sagittal plane）的计算。尾鳍节段除外，其仅各设有一个横平面对应的工作表，原因如下：一是假定尾部弯曲不存在背腹方向（冠状平面）的分量；二是由于标本未以完美双侧对称的姿态固定，左右轴（矢状平面）的静水平衡研究价值较低。
