| Sumario: | 1. Description of methods used for collection/generation of data: The flower reflectance spectra were made with USB-2000 and Jaz A1465 Ocean Optics spectrophotometers (Duiven, The Netherlands) equipped with a top sensor system deuterium-halogen standardized light source, DT-MINI-GS-2 and DH-2000 lamps, respectively, and a coaxial fibber cable (QR-400-7-UV-VIS-BX; Ocean Optics). Reflectance corresponds to the proportion of a standard white reference tile (WS-1-SS; Ocean Optics). For all measurements, we kept the distance between the petals and the measuring probe constant and with an angle of illumination and reflection fixed at 45°. Spectra data were processed with OceanView software (version 2.0.8; Ocean Optics) and calculated in 5-nm wide spectral intervals in the range of 300–700 nm. 2. Methods for processing the data: We used the ‘getspec’ function of the ‘pavo’ R-package to load the colour spectral data between 300 and 700 nm of each flower. To reduce noise, the data was smoothed with a span of 0.25 and negative values were corrected by setting the minimum value to zero and scaling other values accordingly (‘procspec’ function). 3. Instrument- or software-specific information needed to interpret/reproduce the data, please indicate their location: USB-2000 and Jaz A1465 Ocean Optics spectrophotometers (Duiven, The Netherlands) equipped with a top sensor system deuterium-halogen standardized light source, DT-MINI-GS-2 and DH-2000 lamps, respectively, and a coaxial fibber cable (QR-400-7-UV-VIS-BX; Ocean Optics). Reflectance corresponds to the proportion of a standard white reference tile (WS-1-SS; Ocean Optics). Spectra data were processed with OceanView software (version 2.0.8; Ocean Optics). 4. Standards and calibration information, if appropriate: Reflectance corresponds to the proportion of a standard white reference tile (WS-1-SS; Ocean Optics). |
