Well my expectation was that having a consistent set of data from the same source was valuable for this study, so Levesque got picked. However ... Betelgeuse doesn't have a luminosity determined in Levesque et al. (2005), because it doesn't have a reliable distance, and the adopted temperature there is 3,650 K not 3,800 K. So clearly the data came from somewhere else. For that alone, I think it should be ignored. Further, Levesque & Massey (2020) quote a temperature of 3,600 K so I don't think there is much reason to change this in the article. Similarly, the distance of 130 pc is pretty obsolete, not even the new Hipparcos reduction, but the original one. I didn't look into the underlying reference to see why. No idea where the luminosity came from. Perhaps based on the lower distance, perhaps from one of the other references. I don't think we can use any of it.
