These can be used to reconstruct a full nested sampling run, as well as simulate dynamic nested sampling. The format & contents of these two files are as follows: They have has ndims+nderived+2 columns. The first ndims+nderived columns are the ndim parameter values along with the nderived additional parameters that are being passed by the likelihood routine for PolyChord to save along with the ndims parameters. The ndims+nderived+2 column is the log-likelihood value. The ndims+nderived+1 column is the log-likelihood value that the point was born at. They are is identical to the [root]_phys_live.txt and [root]_dead.txt file, except for an additional column including the birth contours
The way I understand this the order of the columns for n sampling parameters and m derived parameters is supposedly:
That's certainly what the anesthetic reader assumes, and (fortunately!) that's also what the polychord code does. I'll update the readme now. Many thanks @lukashergt
In the README.rst it says:

Could you confirm/refute that suspicion, @williamjameshandley ?
