Notes.
X-ray: the uncertainty interval of the Chandra X-ray absorption-line redshift in SW (F10) and PC (Z10), LD: the extent (z1–z2) of the LD structure intersected by the H2356-309 sight line. The redshifts refer to the heliocentric frame.
Derived from NH assuming T = 106 K, O abundance of 0.1 solar, and solar O/H ratio from Grevesse & Sauval (1998).
