Summary
| Description |
English: Airglow correction of WD 1647+375 of the deep exposure where the raw spectrum and the best-fitting airglow template are shown in black and red, respectively. The airglow-corrected spectrum is shown in blue and arbitrarily shifted in flux for clarity. The strong absorption lines of Si ii and O i affected by the airglow are marked in the plot. The dashed black line shows the average continuum flux in the wavelength region 1300–1309 Å. |
