Electronic data files as supplementary material for "Colour preferences of Tetragonula carbonaria stingles bees for colour morphs of the Australian native orchid Caladenia carnea" submitted for revision at Journal of Comparative Physiology A JCPA-D-18-00116

README file corresponding to the supplementary electronic data for "Colour preferences of Tetragonula carbonaria stingles bees for colour morphsof the Australian native orchid Caladenia carnea" (JCPA-D-18-00116) by:<br>Dyer Adrian G., Boyd-Gerny S, Shrestha M, Garcia Jair E., van der Kooi C, Wong Bob B. M<br>The submission consists on 10 files written using CSV-UTF8 on a Machintosh computer (LX- line ending)containing colour distances (dC), corresponding probabilities of discrimination (Pi) matrices for the individual orchids measured as part of the study and two files _reflectance containing spectral data from 300 to 650 nm at 10 nm intervals used to calculate the colorimetry reported in the paper. <br>Two colour distance metrics wereused for the distance matrices: Euclidean distances in the colour hexagon of Chittka 1992 (HEX) and colour difference in the receptor noise space (RN) by Vorobyev and Osorio 1998. <br>Colour distances and associated discrimination probability were calculated for twosets of samples: three C. carnea orchids collected in the field (WILD) and three orchids provided by teh Australasian Native Orchid Society (ANO). Files are thus named followingthe convention ORCHIDORIGIN_COLOURMODEL_DISTANCEORPROBABILITY. For example hexagon colour distances for orchids sampled in the field are located in the file:WILD_HEX_dC.csv, whilst probabilities of discriminate colour distances in receptor noiseunits for an orchid provided by the Australasian Native Orchid Society will be inANO_RN_Pi.csv.<br>For the .CSV files formatted as a distance matrix, the labels of the rows for the WILD orchid matrices are:BLANK, ALG, WDS1, WDS2, WDS3, WLS1, WLS2, WLS3, WP1, WP2, WP3, PDS1, PDS2, PDS3, PLS1, PLS2, PLS3, PP1, PP2, PP3and for the columnsALG, WDS1, WDS2, WDS3, WLS1, WLS2, WLS3, WP1, WP2, WP3, PDS1, PDS2, PDS3, PLS1, PLS2, PLS3, PP1, PP2, PP3<br>The columns abbreviations are the same ones used for the figures of the main manuscript:W for white morphP for pink morphDS for dorsal sepalLS for lateral sepalPP for petal.Numbers following each abbreviation identify the different individuals. ALG is the adaptation background(average Australian foliage) and BLANK is just the first (empty) cell of the matrix. <br>ANO orchids follow the same abbreviation rule for the WILD orchids but, this data lack the petal readings (PP).<br>Headers of the reflectance files follow the same abbreviation rule as the columns of the distance matrices, but the first column is called LAMBDA rather than BLANK and it contains the spectral interval corresponding to the reflectance measurement for each orchid sample.<br>Files were compiled by Garcia Jair E. on March 7 2019. The authors have done every effort to ensure data is correctlyformatted and free of error or bugs at the time of compilation. <br>
