Photometric and Spectral Data of Galactic Wolf-Rayet Stars (WN sequence)
Listed in IVOA Registry (Virtual Observatory)
This catalogue contains results of **photometric and spectral observations** of eleven Galactic **Wolf–Rayet stars** of the **WN sequence**, obtained in 2021–2022 at the *Fesenkov Astrophysical Institute (FAI), Kazakhstan*.
Description
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 measurement of 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 **He II λ4540**, **N III λ4619**, **He II λ4685**, **He II + H I λ4859**, **N V λ4945**, **He II λ5411**, **He II λ6560**, **He II λ6583**, and **N IV λ7109**. These data were **first published** in the paper *“Photometric and Spectral Studies of a Group of Galactic Wolf–Rayet Stars. I. WN Sequence”*, *Astrophysics*, **Vol. 66, No. 4 (November 2023)**, by *L.N. Kondratyeva, I.V. Reva, E.K. Denisyuk, S.A. Shomshekova, A.K. Aimanova*. DOI: `10.54503/0002-3051-2023.76.4-521`
