849:"In this work we present the full astrometric orbit and barycentric motion of Luhman 16 AB and the first precision measurements of the individual component masses. We draw upon archival observations spanning 31 years from the European Southern Observatory (ESO) Schmidt Telescope, the Deep Near-Infrared Survey of the Southern Sky (DENIS), public FORS2 data on the Very Large Telescope (VLT), and new astrometry from the Gemini South Multiconjugate Adaptive Optics System (GeMS). Finally, we include three radial velocity measurements of the two components from VLT/CRIRES, spanning one year. With this new data sampling a full period of the orbit, we use a Markov Chain Monte Carlo algorithm to fit a 16-parameter model incorporating mutual orbit and barycentric motion parameters and constrain the individual masses to be~27.9+1.1−1.0~MJ for the T dwarf and~34.2+1.3−1.1~MJ for the L dwarf."

same as those updating the associated tables. Is this something we need to bring up with
Knowledge (XXG) proper so that a uniform procedure can be developed that ensures the text and table data remain in agreement whenever updates are made? When such discrepancies exist, the reader has no way of knowing which data element is the correct one.
553:
That explains why there are discrepancies. Not knowing which data element is correct (the text or the table) is the reason why it would have been irresponsible for me to change one or the other. Thank you for making the correction; you have greater skill than I do with finding the correct data from
471:
A source is not necessarily obsolete just because it is from a few years ago; in this case, in this situation, it is a case of improved technology and a much greater range of observations which provides what should be more accurate data. Also, it is extremely unlikely that you'll ever see a notice on

The article's text indicates an orbital period of 27 years, but the article's side table indicates ~45 years. I have noticed text-vs-table discrepancies for many

At the place where this system would be, Sirius is the brightest star, followed by
Canopus, followed by Alpha Centauri A, then a number of other stars, and finally the Sun at 1.33m. The Alpha Centauri system is also the closest neighbor at 3.8 to 3.9 light years distance, followed by the Sun at 6.5

The article indicates 34 and 27 Jupiter masses, respectively. Has it been finalized which is more accurate -- the article text, table, or the source you reference? Identifying accuracy must be a challenge for the authors when the different source documentation (atronomical scientific papers)

Had I understood that a source dated 2013 was obsolete, I would not have commented. I apologize if my ignorance was frustrating Since there was no notation in the talk page that the source was obsolete, it confused me. Then again, I am easily confused.
