Real World Records 1/2 speed Remasters

Trying to determine if the recent 33 & 1/3 half speed re-masters of Peter Gabriel's catalog on Peter Gabriel's label
on Real World Records are:

1. Analogue or digital masters?

2. Original masters used for the above referenced reissues?

I didn't see anything on his site stating type of recording process or generation of master used.
Anyone that may know; please advise.
BTW, the above ref catalog is on sale at Pop Market, and free shipping for 24 hours from maybe 01/30/2017 12:49 PST
Also curious as to the quality of the new vinyl.   My original vinyl copies are atrocious.  Probably some of the worst mfg. processed LP's I own.  I would listen on Tidal instead, but I don't believe his LP's are on there to play.
I just bought Gabriel's 1st 4 albums on the Real World label. Are these the ones of which you speak? If so, I will report back ASAP with a critique.
