Color indexes

[edit]

@Lithopsian The color indexes you added cant possibly be correct considering the type of this star. B-V is too low and U-B is too high. For example, Arcturus, a similar star, has B-V = +1.23 and U-B = +1.28. Jolielegal (talk) 17:11, 29 January 2023 (UTC)[reply]

Yes, I noticed the U-B was very large, but not many sources give it at all for red giants. Here is one that also has a large U-B, but a more expected value for B-V. The Bright Star Catalogue has values more in line with an early K giant. Here is the only other source I can find. Lithopsian (talk) 17:36, 29 January 2023 (UTC)[reply]
