Woelders et al. (2018). Intensity and color increases time signal stability for the human circadian system when sunlight is obscured by clouds

This Fileset contains all (calibrated) data and R code required to reconstruct the analyses and graphs presented in the article.<br>- 1. rawData contains the calibrated data (added solar angles using analysis/misc/solarAngle.R and cloud cover information from analysis/misc/weather.txt)- 2. finalData contains the processed data, containing Date, Time, Solar Angle, Cloud Cover, Wavelength (nm), W/m2, Photons, Lens transmittance, Transmitted photons, log10 Transmitted photons, CIE x chromaticity, CIE y chromaticity, MacLeod &amp; Boynton smb (S/[L+M]), MacLeod &amp; Boynton lmb (L/[L+M]) and log10 Melanopic photons. This dataframe is constructed from 1. rawData/rawData.RData using the 1. add_chromaticity_effectivePhotons.R script- 3. modelledData contains the modelled data, containing the predicted solar angles from the KNN models constructed using the analysis/2. createKNN.R script- The figures are then created using the FigX.R scripts. The resulting figures can then be found in the 'graphs' folder. The corresponding statistical analyses can also be found in these scripts.

本数据集包含复现论文中所有分析与图表所需的全部（已校准）数据及R语言代码。
1. rawData：存储已校准数据，该数据通过`analysis/misc/solarAngle.R`脚本添加太阳角度信息，并整合了`analysis/misc/weather.txt`中的云量数据。
2. finalData：为经处理后的数据集，包含日期、时间、太阳角度、云量、波长（nm）、辐照度（W/m²）、光子数、透镜透射率、透射光子数、log₁₀透射光子数、国际照明委员会（Commission Internationale de l'Éclairage, CIE）x色度坐标、国际照明委员会（Commission Internationale de l'Éclairage, CIE）y色度坐标、MacLeod与Boynton提出的S/[L+M]（smb）、L/[L+M]（lmb）以及log₁₀黑色素感光光子数。该数据集由`1. rawData/rawData.RData`通过`1. add_chromaticity_effectivePhotons.R`脚本生成。
3. modelledData：存储建模数据集，包含通过`analysis/2. createKNN.R`脚本构建的K近邻（K-Nearest Neighbors, KNN）模型所预测得到的太阳角度数据。
各类图表可通过`FigX.R`系列脚本生成，成品图表可在`graphs`文件夹中获取，相关统计分析代码也包含于这些脚本内。
