"574km" size on Solar System Objects By Size list?

Anyone know where this came from? It doesn't agree with any of the sizes given in the article, unless we maybe consider the 420km lower bound from the magnitude-only range plus one of the 600-ish sizes in isolation. Any other average I can work out from the full data set is in the 600s... 146.199.60.87 (talk) 23:29, 13 August 2019 (UTC)[reply]

Edit: never mind. It was from a more up to date version of Brown's page than was used here; I've adjusted the data on the article to suit. But, on that note, does anyone know where the heck HE gets his data? Because this is far from the first time where I've seen entries on that page which completely disagree with every other available record (e.g. H=4.5 when everyone else says brighter than 4.1), with no indication of what that disagreement is based on. For all we know he could just be rolling dice, and expecting everyone to believe the results are correct because of his unique position within the TNO research community. There's no good sign on the page itself. 146.199.60.87 (talk) 12:05, 14 August 2019 (UTC)[reply]

Mike Brown's absmag H have been wrong since April 2014. See: Talk:List_of_possible_dwarf_planets/Archive_1#H_value_in_Brown's_list. -- Kheider (talk) 01:34, 15 August 2019 (UTC)[reply]
