cds-question@unistra.frquasarsredshiftedline-intensitiesWe present a systematic study of weak intervening CaII absorbers at low redshift (z<0.5), based on the analysis of archival high-resolution (R>=45000) optical spectra of 304 quasars and active galactic nuclei observed with VLT/UVES. Along a total redshift path of {DELTA}z~~100 we detected 23 intervening CaII absorbers in both the CaII H & K lines, with rest frame equivalent widths W_r,3934_=15-799m{AA} and column densities logN(CaII)=11.25-13.04 (obtained by fitting Voigt-profile components).2011A&A...528A..12Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/528/A12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/528/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/528/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/528/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/528/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/528/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/528/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/528/A12/qso (QSO names and related data for the 23 intervening CaII absorbers at z=0-0.5 detected in our QSO (tables 1 and 2 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/528/A12/qso?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/528/A12/qso?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/528/A12/qso?GETtext/xml+votable180.050000true183.788462233.16534420.005555555555555556Cone search capability for table J/A+A/528/A12/tablea2 (List of additional CaII candidate systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/528/A12/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/528/A12/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/528/A12/tablea2?GETtext/xml+votable180.050000true246.162523.753330.005555555555555556Cone search capability for table J/A+A/528/A12/tablea3 (Complete list of QSOs in our data with mean S/N and CaII redshift path (dz))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/528/A12/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/528/A12/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/528/A12/tablea3?GETtext/xml+votable180.050000true0.93333-23.398610.0055555555555555566/0 2 60 175 579 4124 4140 4170 4279 4354 4394 4448 4696 4820 4850 5272 8289 8291 8371 8709 8758 8858 9252 16386 16494 16553 16555 16597 16625 16640 16644 16652-16653 16656 16658 16664 16677 16752 16798 17011 17203 17212 17257 17414 17485 17488 17516 17518 17639 17730 17755 17816 17818 17833 17835-17836 17917 17979 18001-18002 18004-18005 18022 18060 18081 18084 18086 18096 18177 18208-18209 18299 18307 18366 18388 18504 18506 18601 18624 18661 18669 18756 18769 18780 18790 19026 19087 19101 19166 19190 19680 19682 19993 20032 20099 20516 20731 21012 21126 21180 21935 22544 22578 22593 22754 22917 23045 23190 24809 24845 24941 25009 25054 25117 25120 25285 25294 25302 25344 25413 25427 25628 25697 25829 25934 25950 25961 25965 25976 26000 26100 26115 26165-26166 26175 26195-26196 26245 26453 26499 26614 26724 26878 27002 27034 27037 27215 27269 27310 27338 27415 27514 27554 27577 27650 27652 27687 27704 27728 27756 27841 27909 28039 28208 28258 28315 28538 28548 29675 31451 31520 31686 33632 33684 33827 33971 34019 34044 34107 34202 34210 34264 34291 34379 34424 34437 34461 34485 34503 34517 34570-34572 34582 34763 34950 35006 35213 35242 35258 35277 35281 35430 35496 35522 35570 35584-35585 35595 35627 35737 35751 35774 35781 35786 35806 35836 35842 35894 35901 35945 35957 36012 36090 36101 36126 36130 36241 36265 36313 36417 36554 36655 36840 38639 38744 38767 38787 38853 38878 39456 40060 40446 43399 43903 44000 44028 44269 44549 44668 44799 44938 45006 45011 45621 46208 46251 46373 46418 46527 46529 46542 46574 46638 46651 46662 46704 46737 46850 46856 46924 46953 46964 47007 47016 47091 48149 48154 48228 48474 48478 48589 48595 48610 48757https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/528/A12?format=asciidefaultJ/A+A/528/A12/qsoQSO names and related data for the 23 intervening CaII absorbers at z=0-0.5 detected in our QSO (tables 1 and 2 of paper)QSOQSO name (JHHMMSS+DDMMSS) \linkRole{Voigt-profile fitting of absorbers }meta.id;meta.maincharprimaryl_logN(NaI)[<= ] Limit flag on logN(NaI)meta.code.errorcharlogN(NaI)?
