cds-question@unistra.frvariable-starsspectroscopyphotometryWe have obtained VR photometry of 447 Cepheid variable star candidates with declinations north of -14{deg}30', most of which were identified using the Northern Sky Variability Survey (NSVS) data archive. Periods and other photometric properties were derived from the combination of our data with the NSVS data. Atmospheric parameters were determined for 81 of these stars from low-resolution spectra. The identification of type II Cepheids based on the data presented in all four papers in this series is discussed. On the basis of spectra, 30 type II Cepheids were identified while 53 variables were identified as cool, main sequence stars and 283 as red giants following the definitions in Paper III. An additional 30 type II Cepheids were identified on the basis of light curves. The present classifications are compared with those from the Machine-learned All Sky Automated Survey Classification Catalog for 174 stars in common.2013AJ....146...61Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/61CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2013)J/AJ/141/53 : Lick indices of type II Cepheid candidates (Schmidt+, 2011)J/AJ/139/2026 : TAOS variable stars (Mondal+, 2010)J/AJ/138/466 : NSVS variables automated classification (Hoffman+, 2009)J/AJ/137/4598 : VR light curve of ASAS-North Cepheids (Schmidt+, 2009)J/AJ/133/665 : Photometry of type II Cepheid candidates (Schmidt+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/146/61https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/146/61http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/146/61https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/146/61https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/146/61http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/146/61GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/146/61/photo (Parameters from NSVS photometry (table1) and light curve parameters from the Behlen photometry (table5))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/146/61/photo?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/146/61/photo?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/146/61/photo?GETtext/xml+votable180.050000true1.05462549.70408330.005555555555555556Cone search capability for table J/AJ/146/61/table9 (Known Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/146/61/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/146/61/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/146/61/table9?GETtext/xml+votable180.050000true66.13738724.12335560.0055555555555555566/98 227 242 321 503 509 859 862 872 940 999-1000 1014 1225 1249 1411 1421 1432 1492 1501 1533 1551 1599 1675 1678 1704 1829 2002 2030 2138 2230 2269 2325 2344 2365 2391 2459 2472 2474 2499 2528 2530 2542 2589 2632 2641 2644 2675 2684 2692 2711-2712 2715-2716 2746 2760 2771 2776 2791 2798-2799 2817 2830 2863 2956 2960 3022 3052 3060 3075 3131 3202 3285 3459 3827 3875 3942 3952 3958 4012 4137 4338 4482 4510 4769 5016 5018 5080 5109 5278 5304 5438 5515-5516 5544 5563 5591 5629 5631 5708 5765 5799 5804 5900 5932 5971 6019-6021 6036 6083 6307 6347 6371 6386 6415 6440 6501 6504 6523 6647 6677 6695 6707 6770 6811 6910 6993 7026 7109 7186 7188 7320-7321 7333 7340 7552 7875 7914 8040 8171 8290 8529 8554 8701 8723 8955 9074 9106 9127 9135-9136 9151 9166 9205 9207 9209 9213 9281 9298 9312 9356 9393 9408 9430 9462 9497 9528 9589 9616 9620 9653 9655 9680 9682 9693 9695 9698 9711 9724 9746 9783-9784 9812 9949-9950 10066 10072 10143 10216 10352 10362 10486 10554 10565-10566 10620 10633 10656 10666 10708 10716 10721 10886 10961 11007 11070 11097 11161 11177 11277 11340 11342 11441 11948 11962 12321 12477 12715 12816 12893 12912 12920 13067 13118 13137 13158 13160 13162 13164 13182 13372 13407 13416 13419 13421 13442 13456 13469 13512 13522 13538 13547 13562 13592 13627 13672 13703 13707 13729 13732 13735 13746 13799 13802 13804 13813-13814 13817 13863 13867 13896-13897 13900 13910 13955 14086-14087 14092-14093 14321 14324 14328 14384 14388 14462 14475 14480 14508 14518 14522 14572 14778 14839 14845-14846 14850 14858 14860 14865 14882-14883 14891-14892 14894 14914 14937 14948 14971-14972 14978 14988 15023 15045 15065 15097 15113 15139 15165-15166 15174 15178 15193 15216 15222 15255-15256 15277 15310 15315 15461 15538 15550 15698 15879 15912 15959 16075 16173 16246 16260 16264 16293 16333 16335 16887 17707 18647 18754 18892 18941 19110 19145 19340 19413 19570 19587 19680 19684 19952 20152 20158 20307 20336 20349 20427 21234 21326 21431 21622 21630 21950 21994 22114 22149 22207 22589 22658 22747 22804 22854 22856 22909 22952 23023 23332 23537 23549 23740 23841 23885 23903 24062 24153 24213 25413 25833 25869 25920-25921 26010 26110 26131 26219 27321 27695 28046 28314 28340 28590 28592 28667 29583 29758 29764 30000 30063 30108 30225 30588 30646 30927 31015 31057 31098 31456 31505 31699 31703 31744 31775 31778 31799 31883 31902 31914 31920 31948 32012 32058 32240 32479 32582 32586 32589 32606-32607 32612-32613 32619 32622 32632 32637 32650-32651 32658 32661 32663 32681 32705-32706 32716 32731 32739 32749 32751 36604 36705 36725 40725 40795 40905 40929 44786 44989 45016 48880 49026https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/146/61?format=asciidefaultJ/AJ/146/61/photoParameters from NSVS photometry (table1) and light curve parameters from the Behlen photometry (table5)NameStar designation (JHHMMSS.ss+DDMMSS.s)meta.idcharONameOther name (1)meta.idchar<mag>[8.75/15.82]?
