Two Ni IIλ1393 absorption lines towards HE 0027–1836 at zabs = 2.40156 and 2.40185, occurring on the blue end of the extended Si IVλ1393 absorption (lower panel) together with the corresponding Si IVλ1402 profile (upper panel). The fit (red curve) obtained with our Ni IIλ1393 f-value is superimposed onto the observed spectrum (black line). At vhelio = 0 km s−1, the redshift is z = 2.40185.
