Table D.1

Description of the content for the catalogue of 8846 spectra whose full table is available at the CDS.

Label Unit Description

DATEOBS Date and time of the observation
CNAME Sexagesimal, equatorial position-based source name in the form: hhmmssss+ddmmsss
Thus the CNAME of an object at 3h 40m 21.s767 and –31°2032.71 is 03402177-3120327
RA ° RA (J2000)
Dec ° Dec (J2000)
Halpha_lambda_1 Å five comma separated values – first five solutions of the fit ordered by for the central
wavelength of the first Gaussian profile
Halpha_sigma_1 Å As Halpha_lambda_1 but for the σ parameter of the first Gaussian profile
Halpha_peak_1 As Halpha_lambda_1 but for the height of the peak of the first Gaussian profile in units of normalised flux
Halpha_lambda_2 Å As Halpha_lambda_1 but for the central wavelength of the second Gaussian profile
Halpha_sigma_2 Å As Halpha_lambda_1 but for the σ parameter of the second Gaussian profile
Halpha_peak_2 As Halpha_lambda_1 but for the height of the peak of the second Gaussian profile in units of normalised flux
Halpha_lambda_neb Å As Halpha_lambda_1 but for the central wavelength of the nebular Gaussian profile
Halpha_sigma_neb Å As Halpha_lambda_1 but for the σ parameter of the nebular Gaussian profile
Halpha_peak_neb As Halpha_lambda_1 but for the height of the peak of the nebular Gaussian profile in units of normalised flux
Halpha_neb_indication 0 - no indication of nebular emission, 1 – presence of [N II] emission in object spectrum, 2 –
presence of Hα and [N II] emission in sky spectra (see Appendix A.2)
Halpha_red_chi five comma separated values – for first five solutions of the fit
Halpha_red_chi_f five comma separated values – for first five solutions of the fit
Halpha_flag Flag of spectrum obtained from our ruleset in Fig. B.1 (see text)
Halpha_category Category obtained from our classification scheme in Table 2 (see text)
Halpha_intrinsic 1 for intrinsic stellar emission, otherwise NULL (see text)
