Proxima is already in the catalogue. It's part of the Alpha Centauri system. Are there new parameters in this PR that are on in the Alpha Cen file yet?

ajtribick commented 8 years ago

The Alpha Centauri file only contains the A and B stars. Since both Wertheimer & Laughlin (2006) and Matvienko & Orlov (2014) find quite high probabilities that Proxima is not a bound member of Alpha Centauri (and as far as I can see, the question of whether Proxima is part of Alpha Centauri has not been addressed with the latest RV data that was used to discover Proxima b), I put it in a separate file.

You are right, I forgot to push my local changes. Still not sure about the separate file.

Ok, will close this one for now. It might be worth adding the error bars and the type="msini" to the mass value for Proxima b. Incidentally the mass conversion appears to be off, 1.27 Earth masses = 0.004089 Jupiter masses implies a Jupiter mass of 310.5 Earth masses, the usual values I find are around 317.8.
