cds-question@unistra.frmorgan-keenan-classificationThe catalog contains MK spectral classifications for 1003 HD stars in the zone +25-30{deg}, briefly presented at IAU Colloq. 47, held in Vatican City in July 1978 (1979RA......9..479C). Most stars classified in this region are earlier than G2. The notation is the same as in the earlier paper (1981A&AS...45..455J), with conventions similar to the Houk and Cowley survey (Cats. III/31 and III/51); a noticeable exception is that the luminosity class the most probable stands before the slash. On the average, the classifications present in the catalogue are means of 3 classifications. The internal rms error estimated by the author on a single classification is typically: {sigma}(SpT) = 0.65 (unit 1 subtype) {sigma}(Lum) = 0.40 (unit lum. class) No dependence on spectrum quality is found; however the quality 4 spectra are seldom classified without slashes (which introduces a sort of "internal scatter" into the type) External errors were estimated by a comparison with published work: - Walborn (1971ApJS...23..257W) and Guetter (1968PASP...80..197G) concern early-B stars; - Cowley et al. (1969AJ.....74..375C) and Osawa (1959ApJ...130..159O) concern late-B and A stars; - Harlan et al. (1969AJ.....74..916H, 1970AJ.....75..165H), Hill et al. (1976MmRAS..82...69H) and Heard (1956PDDO....2..105H) concern F stars; - Fehrenbach lists concern all type stars. The comparisons give the following external errors: ----------------------------------------------------- Source N D(SpT) +/- D(Lum) +/- ----------------------------------------------------- Walborn (1971) 5 -.40 +/- .45 -.10 +/- .32 Guetter (1968) 4 -.12 +/- .25 -.12 +/- .25 Cowley et al. 17 -.52 +/- .72 -.09 +/- .53 Osawa (1959) 18 -.22 +/- .77 -.22 +/- .77 Harlan et al. 20 +.20 +/- .69 +.03 +/- .56 Hill et al. 18 -.36 +/- .78 -.19 +/- .55 Heard (1956) 46 -.24 +/- .88 +.10 +/- .47 Fehrenbach et al. 46 +.48 +/-1.39 +.34 +/-1.06 ----------------------------------------------------- These figures should be compared with e.g. Heck and Mersch (1980A&A....83..287H, 1980A&A....85...93M), Cowley et al. (1969AJ.....74..375C), Cowley (1976PASP...88...95C), or Abt (1981ApJS...45..437A)Private communication to the CDS (1982)https://cdsarc.cds.unistra.fr/viz-bin/cat/III/75BCatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=III/75Bhttps://vizier.iucaa.in/viz-bin/VizieR-2?-source=III/75Bhttp://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=III/75Bhttps://vizier.cds.unistra.fr/viz-bin/votable?-source=III/75Bhttps://vizier.iucaa.in/viz-bin/votable?-source=III/75Bhttp://vizieridia.saao.ac.za/viz-bin/votable?-source=III/75BGETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table III/75B/main (The catalogue of MK classifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/III/75B/main?https://vizier.iucaa.in/viz-bin/conesearch/III/75B/main?http://vizieridia.saao.ac.za/viz-bin/conesearch/III/75B/main?GETtext/xml+votable180.050000true24.70812526.64416670.0055555555555555564/1524 5/276 1547 1550 1551 2595 3196 3199 3255 3259 3261 3262 3263 3275 3277 3279 3296 3304 3342 3352 3360 3364 3601 5053 5067 5092 6007 6014 6015 6075 6093 6094 6095 6100 6113 6114 6115 6116 7120 7121 6/731 732 733 742 747 749 750 751 753 754 755 757 758 759 760 762 763 765 905 906 907 910 929 930 931 934 936 937 938 1093 1094 1095 1100 1101 1108 1110 1112 1113 2077 2079 2101 2113 2114 2115 2117 2118 2119 2120 2121 2125 2130 2131 2132 2134 2137 2138 2144 2145 2147 2150 2160 6181 6182 6183 6187 6193 6194 6198 6272 6273 6275 6276 6278 6279 6280 6281 6282 6284 6285 6287 6288 6290 6291 6294 6304 6305 6306 6308 6309 6312 8937 8941 8942 8947 8954 8955 10263 10270 10271 10278 10279 10283 10285 10286 10287 10291 10292 10293 10295 10297 10299 10301 10302 10305 10306 10307 10309 10312 10314 10315 10316 10317 10322 10336 10370 10371 10372 10373 10375 10379 10384 10385 10400 10401 10404 12759 12766 12767 12781 12788 12791 12795 13033 13035 13041 13042 13043 13085 13087 13099 13105 13106 13107 13114 13115 13120 13121 13122 13124 13126 13128 13134 13135 13136 13141 13142 13146 13152 13153 13154 13156 13157 13162 13189 13190 13191 13193 13194 13195 13197 13198 13199 13200 13201 13204 13205 13208 13209 13210 13224 13225 13335 13339 13340 13342 13351 13356 13357 13359 13361 13362 13363 13364 13365 13366 13372 13373 13375 13378 13379 13381 13383 13384 13386 13387 13388 13390 13391 13395 13396 13398 13400 13414 13416 13417 13445 13447 13448 13450 13452 13453 13455 13460 13461 13462 13464 13472 13473 13474 13477 13478 14401 14403 14412 14413 14415 14416 14418 14419 14420 14422 14424 14425 14426 20187 20188 20206 20208 20210 20216 20218 20219 20220 20221 20222 20267 20355 20358 20359 20360 20361 20363 20364 20365 20366 20378 20386 20387 20392 20393 24022 24023 24027 24037 24039 24043 24045 24046 24047 24049 24050 24051 24052 24053 24054 24279 24281 24283 24284 24305 24306 24311 24313 24314 24315 24316 24317 24318 24343 24346 24347 24350 24351 24359 24362 24363 24365 24366 24367 24369 24370 24408 24410 24418 24419 24420 24421 24424 24448 24450 24451 24469 24472 24474 24480 24482 24483 24484 24488 24489 24490 28124 28142 28143 28146 28149 28150 28158 28439 28489 28491 28494 28496 28497 28499 28504 28516https://cdsarc.cds.unistra.fr/viz-bin/moc/III/75B?format=asciiOpticaldefaultIII/75B/mainThe catalogue of MK classificationsRemShort remarksmeta.notecharrecnoRecord number assigned by the VizieR team.
