cds-question@unistra.frlate-type-starsmorgan-keenan-classificationa-starsThis is the first in a series of two papers that address the problem of the physical nature of luminosity classification in the late A-, F-, and early G-type stars. In this paper, we present precise spectral classifications of 372 stars on the MK system. For those stars in the set with Stroemgren uvby{beta} photometry, we derive reddenings and present a calibration of MK temperature types in terms of the intrinsic Stroemgren (b-y)_0_ index. We also examine the relationship between the luminosity class and the Stroemgren c_1_ index, which measures the Balmer jump. The second paper will address the derivation of the physical parameters of these stars, and the relationships between these physical parameters and the luminosity class. Stars classified in this paper include one new {lambda} Bootis star and 10 of the F- and G-type dwarfs with recently discovered planets.2001AJ....121.2148Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/121/2148CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/121/2159 : Basic parameters for 372 A, F & G stars (Gray+, 2001)http://nedwww.ipac.caltech.edu/level5/Gray/frames.html :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/121/2148https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/121/2148http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/121/2148https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/121/2148https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/121/2148http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/121/2148GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/121/2148/table1 (MK classifications of late A-, F-, and early G-Type stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/121/2148/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/121/2148/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/121/2148/table1?GETtext/xml+votable180.050000true2.12582852.3364580.0055555555555555566/62 320 333 337 339 342 349 401 460-461 463-464 472-474 485 496 753 757 1005 1024 1032-1033 1035 1100 1287 1436 1603 1728 1749 1769 1962 2127 2317 2340 2420 2436 2472 2477 2598 2650 2691 2749 2812 2898 2923 2940 2980 3001 3005 3016 3020 3031-3032 3036 3043 3051 3060 3102 3118 3138 3230 3239 3270 3274 3301-3302 3305 3336 3342 3606 3623 3625 3632 3641 3645 3679 3724 3849 3996 4028 4418 4698 4709 4720 5154 5230 5311 5323 5345 5392 5490 5522 5586 5830 5985 6106 6184 6255 6516 6776 6941 7178 7763 8274 8306 8466 8476 8478 8534 8592 8772 8803 8843 8845 8935 8985 8995 9072 9125 9327 9403 9442 9476 9546 9553 9759 9774 9913 9995 10055 10367 10375 10459 10568 10741 10835 10899-10900 11119-11120 11204 11290 11296 11335 11403 11644 11647 11732 12465 12523 12592 12604 12644 12844-12845 12899 12944 12962 13004 13007 13099 13166 13195 13201 13222 13277 13407 13440 13478 13497 13697 13725 13878 13955 13961 13994 14001 14045 14055 14073 14131 14139 14180 14214 14224 14246 14253 14308-14309 14320 14384 14425 14469 14522 14544 14548 14609 14616 14619 14621 14643 14649-14650 14672 14690 14700 14779 14899 14906 15174 15263 15279 15366 15376 15494 15621 15760 15962 16105 18290 18978 19045 19237 19323 19507 19547 19585 19733 19802 20118 20145 20178 20184 20220 20278 20460 20828 21112 21788 22300 22806 22947 23096 23190 23230 23236 23339 23369 23438 23454 23523 23526-23527 23532 23535 23537-23538 23544 23547-23548 23820 24218 24743 25559 25617 25869-25870 25930 25963 26465 26521 26575 26967 26975 27130 27268 27909 28008 28017 28136-28137 28151 28437 28439 28481-28482 28486-28487 28489-28490 28494 28544 28551 29157 29183 29518 29525 29864 30221 30293 30439 30475 30510 30576 30578 30660 30665 30694 30915 31125 31416 31433 31698 31929 31933 31976 32109 32120 32192 32204-32205 32552 32590 32613 32619 32645 32674 35823 36149 38806 39768 39868 39923 40466 40593 40932 42988 44129 45032 48886https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/121/2148?format=asciiOpticaldefaultJ/AJ/121/2148/table1MK classifications of late A-, F-, and early G-Type starsSpTypeSpectral type (4)src.spTypecharrecnoRecord number assigned by the VizieR team.
