MEGARA spectra of the pointings in the first night (four in the blue range, three in the red), in the observed wavelength frame. Top. The LR-B spectra, centered in the wavelength range from Hβ to [O III] 5007. Bottom. The LR-R spectra, from [N II] 6583 to [S II]6731. The emission lines of interest are marked in both plots. The lines that are not marked are sky emission lines, with Hα being contaminated by one.
