Differences between the abundance from a selected ion of a given element in HR 6000 and the solar abundance, as they are listed in Col. 3 of Table 4. The arrow for Na, Cl, Co, Zn, Ge, Sr, and Zr indicates an upper abundance limit. The vertical full line indicates the jump from Z = 57 to Z = 77, a range in atomic numbers for which no elements were observed in HR 6000. The errors can be inferred from Col. 1 of Table 4.
