cds-question@unistra.frinfrared-sourcesplanetary-nebulaeinfrared-photometryWe study the optical spectral properties of a sample of stars showing far infrared colours similar to those of well-known planetary nebulae. The large majority of them were unidentified sources or poorly known in the literature at the time when this spectroscopic survey started, some 15 years ago. We present low-resolution optical spectroscopy, finding charts and improved astrometric coordinates of a sample of 253 IRAS sources.2006A&A...458..173Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/458/173CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)II/156 : IRAS Faint Source Catalog, |b| > 10, Version 2.0 (Moshir+ 1989)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/458/173https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/458/173http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/458/173https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/458/173https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/458/173http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/458/173GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/458/173/table3 (List of IRAS fields observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/458/173/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/458/173/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/458/173/table3?GETtext/xml+votable180.050000true13.53208366.6702220.0055555555555555566/1082 1179 1229 3080 3262 3552 3630 3739 3780 4018 9713 13046 13210 13283 13917 14040 14248 14357 14436 14487 14566 14598 14626 14694 14738 15410 15486 15588 15612 15762 18741 20764 20831 20934 21274 21504 21543 21666 21888 21931 22045 22069 22212 22392 22425 22800 22854 22882 22892 23013 23695 23707 23839 24079 24279 24355 24515 25113 28676 28724 28733 28746 28801-28802 28804 28812 28819 28824-28825 28845 28854 28857 28876 28889 28900 28908 28988 28994 29174 29182 29189 29200 29207 29221 29254 29256-29257 29261 29277-29278 29303 29335 29394 29451 29466 29470 29528 29545 29554 29571 29595 29646 30127 30223 30297 30310 30313 30321-30322 30348 30417 30428 30430 30562 30610 30678 30682 30701 30796 32093 32537 34926 36948 37006 37211 37339 37342-37343 37351-37352 37367 37373 37650 37716 37720 37836 37864 37890 37908 37912-37913 37923 37978 38027 38382 38402 38435 39188 39223 39233 39280 39323 39365 39370 39935 40492 40555 41382 41406 41433 41466 41470-41471 41526 41566 41579 41592 41646-41647 41670-41671 41676 41687-41688 41691 41702 41705 41707 41709 41734 41759-41760 41769 41774 41781 41784 41813 41826 41837 41858 41879 41945 41967 42032 42152 42167 42171 42213-42214 42233 42254 42310 42349 42370 42380 42387-42388 42419 42433 42437-42439 42455 42464 42466 42483 42487 42495 42529 42566 42644 42817 42840-42841 42981 43013 43024 43029 43047 43085 43130 43140 43520 43651 44317 47741 48822 48879https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/458/173?format=asciiInfrareddefaultJ/A+A/458/173/table3List of IRAS fields observedrecnoRecord number assigned by the VizieR team.
