Note that these planets are confirmed using a statistical method. The
FPP is below 1 percent, but there is some confusion whether to count
them as confirmed or not.
Updated mass estimate from Marcy et al 2014 where it made sense.
See discussion #78
- no negative masses
- no errorbars largr than mass estimates
