Relative abundances of an element X with respect to Zn (left column), P (central), and S (right), against the [Zn/Fe]. The black squares are for DLAs and the orange diamonds are for the Galactic lines of sight. The abundances are summed among individual velocity components; see Table F.2. The dashed curves show the linear fit to the data and the intrinsic scatter σ_int. The sequences become steeper for elements that are more strongly depleted in dust grains. The panels with shaded areas show relative abundances of elements that share similar nucleosynthetic history.
