cds-question@unistra.frquasarsredshiftedline-intensitiesspectroscopyvisible-astronomyWe test the usefulness of the intermediate ionisation lines AlIII 1860 and CIII] 1909 as reliable virial mass estimators for quasars. We identify a sample of 309 quasars from the SDSS DR16 in the redshift range 1.2<z<1.4 to have [OII] 3728 recorded on the same spectrum of AlIII 1860, SiIII 1890, and CIII] 1909. We set the systemic quasar redshift using careful measurements of [OII]. We then classified the sources as Population A, ex- treme Population A (xA) and Population B, and analysed the 1900{AA} blend using multi-component models to look for systematic line shifts of the AlIII and CIII] along the quasar main sequence. We do not find significant shifts of the AlIII line peak in Pop. B and the wide majority of Pop. A. For Pop. xA, a small median blueshift of -250km/s was observed, motiva- ting a decomposition of the AlIII line profile into a virialized component centred at rest frame and a blueshifted component for an outflow emission. For Pop. B objects, we proved the empirical necessity to fit a redshifted very broad component (VBC), clearly seen in CIII], and analysed the physical implications on a Pop. B composite spectrum using CLOUDY simulations. We find consistent black hole mass estimations using AlIII and CIII] as virial estimators for the bulk of Population A. AlIII (and even CIII]) is a reliable virial black hole mass estimator for Pop. A and B objects. xA sources deserve special attention due to the significant blueshifted excess observed in the line profile of AlIII, although not as large as those observed in CIV 1549.2023A&A...669A.135Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/669/A135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/669/A135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/669/A135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/669/A135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/669/A135https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/669/A135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/669/A135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/669/A135/tableb1 (Measurements of the individual spectral fits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/669/A135/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/669/A135/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/669/A135/tableb1?GETtext/xml+votable180.050000true1.37512523.57444440.0055555555555555566/546 675 689 739 742 2072 2082 2097-2098 2131 2138 2183 2203 2226 2232 2273 2573 4109 4123 4190 4249 4316 4322 4347 4406-4407 4443 4448 4467 4474 4491 4506 4529 4551 4565 4569 4596 4601 4686 4696 4711 4911 4932 4972 5119 5123 5134 5138 5151 5153 5176 5218 5231 5271 5353-5354 5393 5556 5577 5624 5633 5693 5703 5723 5753 5787 5872 5878 5902 6025 6117 6162 6224 6483 6496 6526 6644 7210 7266 7291 7336 7433 7536 8221 8234 8346 8370 8373 8440 8466 8791 9076 9134 9180 9225 9328 9374 9380 9456 9489 9517 9625 9784 9859 9936 9970 10021 10030 10034 10144 10146 10277 10394 10498 10537 10566 10571 10577 10633 10673 10706 10798 10817 10873 10916 10959 11104 11172 11206 11276 11278 11323 11346 11431 11527 11531 11535 11813 11945 12523 12751 13332 13380 13402 13417 13580 17242 17650 17656 17682 17684-17685 17701 17715 17730 17753 17769 17775 17779 17784 17797-17798 17802 17809 17847 17860 17862 17870 17898 17951 17959 17965 17985 17999 18052 18056 18075 18078 18089 18095-18096 18101 18131 18145 18183 18189 18212 18224 18256 18286 18313-18314 18386 18390 18404 18417-18418 18749 18775 18780 18803 18810 18845 18856 18901 18906 18919 19034 19052 19067 19069 19094 19122 19136-19137 19169 19212-19214 19493 19532 19537 19576 19635 19656 19687 19723 19741 19761 19808 19828 19888 19918 19929 19933 19952 20046 20061 20121 20130-20131 20163 20166 20184 20188 20198 20218 20248 20257 20290 20298 20328 20363 20410 22013 25939 26088 26095 26300 26609 26878 26951 27215 27253 27481 27530 27549 27586 27702 27714 27759 27788 27858 28070 28078 28098 28134 28198 28215 28276 28297 28351 28399 28480 28506 28550 28552 28643 28652 28666 31406 31413 31695 31723 31730 36858https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/669/A135?format=asciiOpticaldefaultJ/A+A/669/A135/tableb1Measurements of the individual spectral fitsFAlIIIAlIII 1860 Flux (FLUX_ALIII)1e-20W.m**-2phot.fluxfloatrecnoRecord number assigned by the VizieR team.
