Q 0058+019
V = 17.2; z = 1.959; exp = 3000 s; coverage = 3766.2-5791.3 A
Spectra of this QSO, also known as UM 297 and PHL 938, were previously studied by Peterson et al. (1977), Sargent, Boksenberg, & Steidel (1988, SBS), and SS92. An additional tentative Mg II system at z = 0.5230 was reported by SDP (Steidel, private communication), which was not confirmed to an upper 5-sigma EW(rest) limit of 0.05 A.

This system was first reported by SBS and is likely associated with a damped Ly-alpha absorber (Steidel, private communication). A total of seven VP components were fit to the profiles. The Mg I profile is quite interesting in that it occupies roughly an 80 km/s region as compared to the 140 km/s spread of the saturated portion of the Mg II profile. Mn II appears to trace the Mg I, whereas Fe II appears to trace the overall Mg II. It could be inferred that differing ionization and/or chemical conditions are kinematically subclustered (e.g. Lanzetta & Bowen 1992). The Ca II 3934, 3969 doublet was not covered by the HIRES format. The Fe II 2344, 2374, and 2382 transitions showed no absorption to the EW(rest) limits given in Table 3.8.
z=0.725173 |DATA & VOIGT PROFILES| |EWs & AOD COLUMNS| |VP PARAMETERS|This system has not been reported previously. The absorption profile is found to be a single VP component, based upon the Mg II doublet and a Mg I profile. The Ca II 3934, 3969 doublet was not covered by the HIRES format. The Mn II triplet and the five Fe II transitions given in Table 2.1 showed no absorption to the EW(rest) limits given in Table 3.9.
