Lehner N., Savage B.D., Wakker B.P., Sembach K.R., Tripp T.M. =2006ApJS..164....1L ================================================================================ ADC_Keywords: QSOs ; Spectroscopy ; Spectra, ultraviolet Keywords: cosmology: observations - intergalactic medium - quasars: absorption lines - quasars: individual (HE 0226-4110) Abstract: We present an analysis of the FUSE (Far Ultraviolet Spectroscopic Explorer) and HST (Hubble Space Telescope) STIS E140M spectra of HE 0226-4110 (z=0.495). 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).

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 Ly{beta} line (no detection), the corresponding Ly{alpha} line is redward of the available STIS wavelength range. n = See notes.dat for additional information on the marked systems.
