1991ApJS...77..203J A CATALOG OF ABSORPTION IN THE SPECTRA OF QUASI-STELLAR OBJECTS V. JUNKKARINEN, A. HEWITT, AND G. BURBIDGE Center for Astrophysics and Space Sciences. Mail Code 0111, University of California at San Diego, La Jolla, CA 92093-0111 Received 1990 December 22; accepted 1991 March 11 ABSTRACT This paper contains a compilation of basic information on QSO absorption systems. A total of 724 QSOs are listed in three tables. Table 1 contains 353 QSOs that have absorption-line systems with measured redshifts. The numerous Ly{alpha} forest systems based only on narrow hydrogen lines are excluded from Table 1. Absorption systems with multiple components are listed only once if all of the components fall within a span of 500 km s^-1^. A total of 862 systems with narrow metal lines which we consider to be reliably identified are listed in Table 1. Table 1 contains an additional 260 systems consisting of less certain systems, damped Ly{alpha} systems, and Lyman limit systems that have no detected narrow metal lines. In Table 2 we list 146 broad absorption line QSOs. Fifteen of these have narrow absorption line systems identified, and thus they also appear in Table 1. In Table 3 we give an inhomogeneous list of 240 QSOs in which absorption systems have been seen but not measured. Also shown are histograms of emission redshift, absorption redshift, and (1 + Z_em_)/( 1 + Z_abs_) for the reliably identified narrow metal line systems. Several selection effects are apparent in this collection of data. Subject Headings: galaxies: redshifts - line identifications - quasars ############################################################################ 1992ApJS...81..409J ERRATUM In the paper entitled "A Catalog of Absorption in the Spectra of Quasi- stellar Objects" by V. Junkkarinen, A. Hewitt, & G. Burbidge (ApJS, 77,203(1991]) there is an error in Table l. Because of an error in the computer program used to generate the final version of Table 1, the J2000 coordinates for all the objects are incorrect. The error involves the printed values for the J2000 seconds of time in right ascension and the J2000 seconds of arc in declination. The following table gives corrected J2000 coordinates for all the objects in Table 1 of our paper. Table 1 should be consulted for the 1950 coordinates and to check for coordinates which are poorly known. The J2000 coordinate names in Table 1 are correct (except that a few may change as more accurate coordinates become available for those QSOs with poorly determined coordinates), and the B1950 coordinates and coordinate names are not affected by the programming error. Additional corrections: In Table 3, 1040+015 should be QNB1:49, not QNB1:22. Two references were omitted (the numbers appear in Table 1, but the references are not listed): 1720.
