  1. The traits were specified in column 1 using the following abbreviations: BFT – backfat thickness, BCS – body condition score, HH – hip2hip, DL – depthleft, DR – depthright, VL – volumeleft, VR – volumeright, DPL – distpinleft, APL – areapinleft, DML – distmidleft, AML – areamidleft, DPR – distpinright, APR – areapinright, DMR – distmidright, AMR – areamidright (compare List of Abbreviations and camera trait description in paragraph "Further processing: application "ExT"" and Figure9). Coefficients of determination had been calculated restricted to individual cows (R2 cow , mean and maximum in brackets, all minimums zero) and for the whole datasets using a generalized linear model with a piecewise linear link function (R2). Last columns contain the correlations to BFT (corrBFT) and BCS (corrBCS), p = 0.05, "NS" indicates that the linear connection was not significant.
