cds-question@unistra.frstar-atlasesspectroscopyearly-type-starslate-type-starsWe have assembled an atlas of line profiles of the Paschen Delta (P-{delta}) line at 10049{AA} for the use of stellar modelling. For a few stars we have substituted the Paschen Gamma (P-{gamma}) line at 10938{AA} because the P-{delta} line blends with other features. Most of the targets are standard stars of spectral types from B to M. A few metal-poor stars have been included. For many of the stars we have also observed the Hydrogen Alpha (H-{alpha}) line so as to compare the profiles of lines originating from the meta-stable n=2 level with lines originating from the n=3 level. The greatest difference in line profile is found for high luminosity and cool stars where the departures from LTE in the population of the n=2 level is expected to be the greatest. For a few stars, sample line profiles have been calculated in the LTE approximation to demonstrate the usefulness of the tabulated and displayed catalogue.2012A&A...547A..62Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/547/A62CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/547/A62https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/547/A62http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/547/A62https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/547/A62https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/547/A62http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/547/A62GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/547/A62/standard (List of standard stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/547/A62/standard?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/547/A62/standard?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/547/A62/standard?GETtext/xml+votable180.050000true84.0533889-1.20191920.005555555555555556Cone search capability for table J/A+A/547/A62/metalp (List of metal-poor stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/547/A62/metalp?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/547/A62/metalp?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/547/A62/metalp?GETtext/xml+votable180.050000true7.8204775-16.79466530.0055555555555555566/1198 1460 1556 1759 1989 2282 2426 2921 2970 2997 3060 3138 3229 3247 3250 3254 3256-3257 3274 3276 3284 3637 3712 3932 4266 4419 4574 5109 6166 6674 6897 7402 8767 9419 9441 9520 9680 11599 12544 12882 12934 13392 13411 14209 14711 14906-14907 15392 15633 15650 15747 16821 17138 17578 18553 18978 19045 19323 19676 20313 20390 21939 22787 22862 23540 23611 23621 23864 23979 23995-23996 24164 24186 24336 24370 24504 25659 26457 27498 28664 29769 30128 30293 30709 31757 32271 44542https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/547/A62?format=asciiOpticaldefaultJ/A+A/547/A62/standardList of standard stars observedrecnoRecord number assigned by the VizieR team.
