CSIRO museum egg color data

This workbook contains data related to the museum egg color analyses and only includes data from the eggs at the CSIRO museum in Canbera, ACT, Australia or eggs from the field in Sydney, NSW and Canberra, ACT that were blown prior to measuring. The first sheet contains the average spectrophotometric data at each wavelength for each clutch and koel egg, which was used to determine the color catch cone values (second sheet). The second sheet contains the color catch cone values for all four avian color cones (VS, SWS, MWS, LWS) and the double cone for luminance. These color catch cone values were used in the discriminate function analysis to determine if koels exhibit host-specific races in color and the color catchcone values were also used to calculate Just Notcieable Differences (JNDs) to compare egg colors and luminances between species. For more information about each clutch, please see the supplemental material in the manuscript. For more information about the analyses, please see the Methods and Results section in the manuscript.

本工作簿收录与博物馆卵色分析相关的数据集，仅包含两类样本：其一为澳大利亚首都领地堪培拉的CSIRO博物馆馆藏卵，其二为产自澳大利亚新南威尔士州悉尼与首都领地堪培拉的野外卵（此类野外卵在测量前已通过吹卵法完成内容物排空处理）。第一个工作表收录每窝卵与噪鹃（Koel）卵在各波长下的平均分光光度数据，该数据被用于计算色捕获锥体细胞（color catch cone）数值，对应结果收录于第二个工作表。第二个工作表则包含四类鸟类色锥体细胞（VS、SWS、MWS、LWS）以及用于亮度计算的双锥体细胞的色捕获锥体细胞数值。上述色捕获锥体细胞数值被应用于判别函数分析（discriminant function analysis），以探究噪鹃是否在体色上存在寄主专化宗；同时该数值也被用于计算恰可察觉差（Just Noticeable Differences, JNDs），以此比较不同物种间的卵色与亮度差异。若需了解每窝卵的详细信息，请参阅对应论文的补充材料；若需了解本分析的具体方法与细节，请参阅该论文的“方法与结果”章节。
