Accuracy level needed for measurements of HWP parameters h, β, and ζ in order to keep the bias on r below Δr = 5.7 × 10−6. Threshold values are given for individual LiteBIRD MFT frequency bands and one band for each of LFT and HFT (quoted with their band centers). The total MFT threshold is set by the lowest threshold in the MFT bands.
