Notes. Uncertainties listed are the formal 1σ errors on the Gaussian fit. Lower limits identified by >, upper limits by <.

(a)

Non-detection.

(b)

Marginal detection.

(c)

Possible blend, systemic velocity assumed.

(d)

Negatives indicate optical depth of absorption.

(e)

1σ rms.

(f)

Foreground.

(g)

Pointing offset between N2H+ APEX observations and HIFI.

(h)

Lines blended. systemic velocity assumed and lines fit simultaneously.
