**Table 3:** Atomic data for the isotopic components of Ca II $\lambda$ 8498 Å.
$\lambda$ (Å)	isotope	$\log gf\varepsilon$
8498.023	40	-1.43
8498.079	42	-3.60
8498.106	43	-4.29
8498.131	44	-3.10
8498.179	46	-5.81
8498.223	48	-4.14

The fractional abundance of Ca isotopes, $\varepsilon$ , corresponds
to the composition of the terrestrial matter.
