Yes, I saw the scores but just thought you might have saved the lines as well. Good luck in your corresponence analysis. >I also found small advantage for white when I gave it to analyze some minutes >after Nxd3 but the score was not convincing(I do not remember it but >I am sure that it was less than 0.5 pawns for white) I guess my intention was to engage in a process that often occurs on this site. Two or more people sharings actual move sequences, refining, re-analyse ... then after some hard work, especially in this position, possibly come up with a clearer understanding of of the moves. FWIW using Tiger13 and own input of move choices I'm coming up with plus scores for white in all the alternatives you proposed. In some lines a common theme occurs of an eventual f3 by white followed by Kf2 or Kg2 then the rook shifting to h1. It was a fun exercise but given the depth and many alternatives I would not be 100 convinced either.
