The 3,400 K estimate refers to the range of spectral types in NGC 7419, (M0-M7.5) and their corresponding temperatures (3400-3800 K). The 3,000 K temperature in the newer source comes from real data and is not an assumption. Nussun05 ( talk) 13:20, 20 December 2020 (UTC) reply

Also even if it was, the data is from 2013, which is a bit significantly older than the new source. Nussun05 ( talk) 07:57, 4 January 2021 (UTC) reply
