VizieR Online Data Catalog: HD 183656 Long-term variations (Wolf+, 2021)

table1.dat: All RVs from the literature, edited and corrected for misprints. Data sources are identified by spectrographs numbers (Spg.No.) identical with those in Table D.2.

table2.dat: All RVs with their rms errors (in km/s) measured on electronic spectra at our disposal. Data sources are identified by letters identical to those from table D.1. Missing values are denoted by 9999.99.

table3.dat: Spectrophotometry of Hα line from various published papers. Whenever needed, we measured intensities on the enlarged plots of published Figures with Hα profiles. Spectra published by Catanzaro (2013A&A...550A..79C, Cat. J/A+A/550/A79) were downloaded and re-measured by us.

table4?.dat: Spectrophotometric quantities measured on electronic spectra at our disposal for all five considered spectral lines. No meaningful FWHM values can be obtained for the double emission line Hα and the blend of HeI 6678 / FeII 6677. Sources of spectra are identified by letters in column "File", which correspond to those in table D.1. Missing measurements are denoted by 9.9999.
