This catalogue contains results of photometric and spectral observations of seven Galactic Wolf–Rayet stars of the WC and WO sequences, obtained in 2021–2022 at the Fesenkov Astrophysical Institute (FAI), Kazakhstan.

The observing programme included moderately bright stars (mostly fainter than V = 10m) observed in B, V, and Rc photometric filters, as well as medium-resolution spectra for measuring absolute fluxes in prominent emission lines.

For each object, the table provides:

• identifiers (WR catalogue number, alternative name),
• spectral subtype,
• equatorial coordinates (J2000),
• literature photometry (B_cat, V_cat) and reference codes,
• date of observation and Julian Date (JD−2400000),
• measured B, V, Rc magnitudes with their errors,

• and absolute fluxes and equivalent widths for a set of emission lines, including

  C III λ4650, He II λ4686, C IV λ5017, He II λ5411, He II + C IV λ6560, C III λ6744, C IV λ7065, and C II λ7234.

These data were first published in the paper “Photometric and Spectral Studies of a Group of Galactic Wolf–Rayet Stars. II. WC and WO Sequences”, Astrophysics, Vol. 67, No. 1 (February 2024), by L.N. Kondratyeva, I.V. Reva, E.K. Denisyuk, S.A. Shomshekova, A.K. Aimanova. DOI: 10.54503/0002-3051-2024.77.1-13
