Notes. Fluxes are corrected for Galactic extinction and slit loss. No correction for host-intrinsic extinction is applied. Upper limits are at 3σ. ( * )Flux estimated using Hα  = 2.86 × Hβ. ( † )[OIII]λ4959 line not detected. We fixed its flux to one-third of the [OIII]λ5007 flux. (#)[OII]λ3729 line falling on a sky line. We fixed its flux to two-thirds of the [OII]λ3726 flux.
