We detect 56 Lyman absorbers and five OVI absorbers. Description: The HST STIS observations of HE 0226-4110 (GO program 9184, PI: Tripp) were obtained with the E140M intermediate-resolution echelle grating between 2002 December 26 and 2003 January 1, with a total integration time of 43.5ks. The FUSE observations of HE 0226-4110 were obtained between 2000 and 2001 from the science team O VI project, and between 2002 and 2003 as part of the FUSE GO program D027 (PI: Savage).

Note (2): Method used, defined as follows: 3σ = for all the nondetections, the 3σ upper limits to the rest-frame equivalent width and to the column density by assuming the absorption lines lie on the linear part of the curve of the growth AOD = apparent optical depth (see Savage & Sembach 1991ApJ...379..245S) FIT = profile fitting

Note (2): Species that cannot be observed because of blending are NULL unless "n" flag is set. Then the species is not observable at this redshift.
Global Notes: Note (G1): Note flags are defined as follows: ! = Possible misidentification, see Section 3.3 for more details; a = The total column densities are presented, but the structure is more complex (see Savage et al. 2005ApJ...626..776S); b = These three system correspond to the 3 absorption lines observed in the system denoted z≃0.27155 in Table 3; c = The limit is based on the Lyβ line (no detection), the corresponding Lyα line is redward of the available STIS wavelength range. n = See notes.dat for additional information on the marked systems.
