Notes. Upper limits are given at the 3σ confidence level.

(a)

Line strongly affected by a sky line. To determine the host galaxy properties we fixed its value to [O ii]λ3729/ 1.5 (low electron density case; Osterbrock 1989).

(b)

Lines falling on too noisy regions to determine a significant upper limit.

(c)

The line is contaminated by a sky line. The flux has been determined by a Gaussian fit, using the part of the line not contaminated by the sky.
