Description:
The tables present photometric monitoring of WR 86 in the Walraven
VBLUW system during two nights in July 1989, three nights in May/June
1990 and six nights in June 1990, together with UBV photometry during
one night in 1995.
Radial velocity measurements of WR86 for six emission lines in 1989,
three emission lines in 1995 and two absorption lines in 1995.
Equivalent width measurements of WR86 for five emission lines in 1989
and three emission lines in 1995.
