J/A+A/412/707  Absorption-line systems in QSO spectra - CoALS (Ryabinkov+, 2003)

A Catalogue of absorption-line systems in QSO spectra -- CoALSs. Ryabinkov A.I., Kaminker A.D., Varshalovich D.A. <Astron. Astrophys. 412, 707 (2003)> =2003A&A...412..707R
ADC_Keywords: QSOs ; Redshifts ; Spectroscopy Keywords: Galaxies: quasars: absorption lines Description: Absorption lines and absorption-line systems (ALSs) observed in the spectra of QSOs contain fundamental information on distribution of matter between the observer and the QSO, and on physical processes in the Universe in different epochs of the cosmological evolution. The presented catalog contains a compilation of basic information on absorption-line systems (ALSs) in QSO spectra. The data are taken from publications available to the authors up to January 2002. The catalog includes, in particular, all the data of the catalogs by Junkkarinen et al. (1991ApJS...77..203J) and York et al. (1991MNRAS.250...24Y ). The catalog consists of table1.dat, table2.txt and the list of references in refs.dat file. The present catalog is also available at the site of the Dept. of Theor. Astrophys. of the Ioffe Physical Technical Institute: <www.ioffe.ru/astro/QC> File Summary:

Note on table1.dat: The table contains data on 821 QSOs whose characteristics of spectral observations are collected in Table 2 (Absorption systems). The data on QSOs are based on the catalog of M.-P. Veron-Cetty & P.Veron (2001A&A...374...92V, Cat. VII/224, superseded by Cat. VII/235 Note on table2.txt: table2.txt contains information on 16139 absorption lines detected in the spectra of 735 QSOs. These lines form 8558 absorption systems. In the spectra of 14 QSOs, only Galactic interstellar lines have been detected; characteristics of these lines are excluded. In the spectra of 72 QSOs, the absorption lines have not been detected or identified. The data were included for reasons of statistical completeness. The file refs.dat contains all numerated literature sources which are indicated in table2.txt.

Note (1): An * in front of the ion designation means "comments" Note (2): Only for heavy-elements and HI lines Note (5): The following symbols are used: 'B' indicates that the line is blended by non-identified ion(s). '?' denotes 'possible' and indicates an uncertainty of detection or identification of the absorption line. '+' following by a name of additional ion designates that the absorption line may be identified also as a line of another ion and may belong to another absorption system with another z_abs indicated in brackets (..). '*' designates comments.

Sign '?' denotes 'possible' and indicates an uncertainty of detection or identification of the absorption line. Sign '+' following by a name of additional ion designates that the absorption line may be identified also as a line of another ion and may belong to another absorption system with another z_abs indicated in brackets (..). Symbol 'nd' designates absence of corresponding data in one of positions described above. Words 'no line list' designates absence of all characteristics (excepting z_abs and the ion's name) of an absorption line identified in the referenced paper. Symbol 'abs' instead of an ion's name indicates that only value z_abs is available in the referenced paper. Words 'no line' designate that absorption lines are not detected or not identified in the observational spectrum. Symbol '*' designates comments. ------------------------------------------------------------------------------- Example: J0001+0709 Q2359+0653 ------------------------------------------------------------------------ 3150 - 4700 A | R = 4.00 A | <S/N> = 40.0 | Zem = 3.234 | [12] 4600 - 7000 A | R = 6.00 A | <S/N> = 60.0 | *wavelength coverage for metal systems: HI emission - 7000 A ------------------------------------------------------------------------ 0.8958 Mg II {2796} 5300.90 0.33 1.22 0.07 {2803} 5315.53 0.35 1.85 0.09 2.7312 C IV {1548} 5777.86 0.38 0.93 0.08 {1550} 5785.03 0.61 0.55 0.09 2.7478 C IV {1548} 5801.40 0.36 1.51 0.09 {1550} 5813.05 0.38 1.68 0.10 + Si IV (3.1724) 2.7801 C IV {1548} 5852.36 0.41 1.14 0.09 + Si IV (3.1724) {1550} 5862.23 0.49 0.58 0.08 2.8641 C IV {1548} 5982.13 0.72 0.55 0.10 {1550} 5992.85 0.51 0.61 0.09 2.9149 C IV {1548} 6060.12 0.39 0.94 0.08 {1550} 6072.11 0.39 0.99 0.09 2.9437 C IV {1548} 6104.87 0.43 0.52 0.08 {1550} 6116.51 0.45 0.72 0.09 2.9872 C IV {1548} 6172.40 0.34 1.65 0.09 {1550} 6116.51 0.45 0.72 0.09 2.9872 C IV {1548} 6172.40 0.34 1.65 0.09 {1550} 6184.05 0.38 2.01 0.11 3.1724 Si IV {1393} 5813.05 0.38 1.68 0.10 + C IV (2.7478) {1402} 5852.36 0.41 1.14 0.09 + C IV (2.7801) C IV {1548} 6459.75 0.34 2.05 0.09 {1550} 6470.39 0.35 1.26 0.08 ------------------------------------------------------------------------ 3250 - 4750 A | R = 4.00 A | <S/N> = nd | Zem = 3.256 | [152] 4550 - 7000 A | R = 6.00 A | <S/N> = nd | *HI emission - 7000 A for metal systems *for DLA W rest,min = 5.0 ------------------------------------------------------------------------ 1.751 DLA 13.8 Byte-by-byte Description of file: refs.dat
