The method of Epchtein et al. (1987A&AS...71...39E) is used to separate oxygen-rich and carbon-rich stars on the basis of their sole NIR and IRAS broad-band fluxes. It is shown that NIR data are necessary to calculate the total IR energy received from IRAS stars and such fundamental parameters as individual mass loss rates. An evolutionary model is developed to match the sequence of stars in color diagrams. It is suggested that the sequence of increasing optical depths might not be an evolutionary sequence, but would rather reflect the termination of a process in which the near-IR index increases very quickly at the beginning and is strongly dependent on the mass loss rate.1990A&A...227...82Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/227/82CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)II/177 : Near IR Photometry of IRAS point sources sample (Fouque+ 1992)III/197 : IRAS Low Resolution Spectra (IRAS team, 1987)J/A+A/334/609 : Carbon stars IR photometry (Guglielmo+ 1998)J/A+AS/99/31 : Identification of C stars in IRAS (Guglielmo+ 1993)J/A+AS/122/489 : New infrared carbon stars in IRAS PSC (Guglielmo+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/227/82https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/227/82http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/227/82https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/227/82https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/227/82http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/227/82GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/227/82/table1a (JHKLM photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/227/82/table1a?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/227/82/table1a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/227/82/table1a?GETtext/xml+votable180.050000true48.138167-57.3215490.0055555555555555566/12543 12970 20602 20615 20811 20981 21338 21425 21560 21638 21683 21897 21912 21959 22052 22069 22093 22096 22099 22225 22235 22237 22239 22330 22362 22446 22809 22941 23526 23548 23628 23630 23640 23642 23667 23733-23734 23778 23846 23855 23942 23962 23966 23971 24070 24142 24258 25486 28724 28818 28826 28895 28899 28917 29166 29214 29443 29462 29519 29524 29531 30217 30232 30240 30244 30261 30271 30415 30428 30569 30593 30628 30644 30661 30716 30942 31831 32003 33589 36986 37193 37210 37223 37238 37320 37328 37343 37347 37350 37366-37367 37374 37400 37405 37689-37690 37716 37719 37734 37752 37756 37833 37863 37866 37871 37894 37922 38019 38066 38078 38117 38304 38406 38409 38428 38433 38441 38450 38462 38505 38509 38656 38999 39246 39285 39290 39323-39324 39342 39368 39375 39384 39396 39523 39705 39751 39773 39790-39791 39805 39911 39920 39924 39982 40064 40066 40072 40094 40117 40150 40157 40168 40464 40601 40673 40691 41045 41328 41530 41571 41583 41586 41596-41597 41623 41630 41650-41651 41663 41688 41692-41693 41701 41705 41708 41711 41738 41742-41743 41765 41776 41781 41786 41801 41803 41805-41806 41825 41832 41904 41910 42124 42138 42152 42165 42167 42173-42174 42181 42189 42205 42208 42218 42221 42223-42224 42231 42233 42236 42280-42281 42351 42369 42375 42377 42435 42440 42444 42463 42496 42515-42517 42560 42845 43020 43024 43028 43030 43039 43045-43046 43055 43264 43525 43581 46318 47664 47752https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/227/82?format=asciiInfrareddefaultJ/A+A/227/82/table1aJHKLM photometryIRASIRAS Numbermeta.numbercharGLONGalactic longitudedegpos.galactic.lonGLATGalactic latitudedegpos.galactic.latfloatrecnoRecord number assigned by the VizieR team.
