The default optical photometry for HD 143466 (HR 5960, CL Dra) is clearly discrepant compared to other published sources (no way this HR star is 9th magnitude in B and V).
For example, the classic UBV photometry reference Johnson+(1966;
1966CoLPL...4...99J
) had V=4.95, B-V=0.26, U-B=0.04 (B=5.21, U=5.25). Moffett & Barnes (1979;
1979PASP...91..180M
) had it as a standard star for BVRI Johnson photometry with V=4.963+-0.013, B-V=0.270+-0.008, V-R=0.249+-0.008, R-I=0.131+-0.011. The Mermilliod 1991 compendium (II/168/ubvmeans) has V=4.957+-0.007, B-V=0.267+-0.005, U-B=0.061+-0.013.
