VizieR Online Data Catalog: Spectro-photometry of 1A 0535+262 (Liu+, 2024)

Optical spectroscopic observations were obtained from two telescopes at two different observatories: most observations from the Xinglong Station of National Astronomical Observatories in Hebei province (China) were made with the spectrometer OptoMechanics Research (OMR) or BAO Faint Object Spectrograph and Camera (BFOSC) on the 2.16 m telescope; other data from the Lijiang station of Yunnan Astronomical Observatory in Yunnan province (China) came from the spectrometer Yunnan Faint Object Spectrograph and Camera (YFOSC) on the 2.4 m telescope.

Table A.1 gives the summaries of the spectroscopic observations. This table contains instrumental information and the results of the spectral analysis: the equivalent widths of the Hα lines and the He I λ6678 lines. Table A.2 gives V/R ratio and peak separation.

Optical photometric observations are obtained from three telescopes at two different observatories: the data from the Xinglong Station of National Astronomical Observatories were made with the 80 cm Tsinghua-NAOC Telescope (TNT) and the 60 cm telescope; the data from the Lijiang station of Yunnan Astronomical Observatory come from the 2.4 m telescope.

In all three telescopes, 1A 0535+262 was observed through the standard Johnson-Cousins B, V, R, and I filters.

The photometric magnitudes are given in Table B.1.
