Description

This 2022 paper, https://doi.org/10.1080/15502724.2023.2166060, claims to give "CCT errors less than 0.1 K throughout the range of 1,500 K to 40,000 K with Duv between −0.05 and 0.05." It involves recalculating the Robertson table and increasing the data resolution. There's also a new interpolation function to handle sign change and a more efficient search method.
