Uncertainties in the NIST spectral standards for detectors and sources in the visible wavelength range are propagated from the high accuracy cryogenic radiometer measurements, taking correlations into account at every stage. Partial correlations between spectral values at different wavelengths, important for subsequent radiometric calculations, are estimated. Uncertainty propagation through fitting and through transfer spectral measurements is described in detail. Detector uncertainties are propagated through the spectral comparator facility for external calibrations and for internal photometric quantities. Uncertainties in spectral irradiance are derived for the detector-based temperature determination, then propagated through working standards to calibrated artifacts. Spectral irradiance calibrations are generally provided at a limited number of wavelengths. Interpolation, rather than fitting, is recommended for the interpolation of NIST-provided spectral irradiance values.
可见波长范围内探测器和光源的美国国家标准与技术研究院（NIST）光谱标准中的不确定度是从高精度低温辐射计测量值传播而来的，在每个阶段都考虑了相关性。估计了不同波长处光谱值之间的部分相关性，这对于后续的辐射度计算很重要。详细描述了通过拟合和通过传递光谱测量的不确定度传播。探测器的不确定度通过光谱比较仪设施进行外部校准和内部光度学量的传播。基于探测器的温度测定得出光谱辐照度的不确定度，然后通过工作标准传播到校准过的工件。光谱辐照度校准通常在有限数量的波长处提供。对于NIST提供的光谱辐照度值的插值，建议采用插值法而非拟合法。
