1  Reanalysis of MD1 data using the electron mass from COHEN 1987, the radiative corrections from KURAEV 1985 and interference effects.
2  Obtained by reanalysing ARGUS and Crystal Ball data (BARBER 1984), but not authored by the ARGUS and Crystal Ball collaboration.
3  Reanalysis of BARU 1986B using new electron mass (COHEN 1987).
4  Superseded by SHAMOV 2023.
5  Reanalysis of ARTAMONOV 1984.
6  Superseded by ARTAMONOV 2000.
7  Reanalysed by SHAMOV 2023.
