cds-question@unistra.frinterferometrystandard-starsinfrared-sourcesThe Palomar Testbed Interferometer (PTI) archive of observations between 1998 and 2005 is examined for objects appropriate for calibration of optical long-baseline interferometer observations - stars that are predictably pointlike and single. Approximately 1400 nights of data on 1800 objects were examined for this investigation. We compare those observations to an intensively studied object that is a suitable calibrator, HD 217014, and statistically compare each candidate calibrator to that object by computing both a Mahalanobis distance and a principal component analysis. Our hypothesis is that the frequency distribution of visibility data associated with calibrator stars differs from noncalibrator stars such as binary stars. Spectroscopic binaries resolved by PTI, objects known to be unsuitable for calibrator use, are similarly tested to establish detection limits of this approach. From this investigation, we find more than 350 observed stars suitable for use as calibrators (with an additional ~140 being rejected), corresponding to >~95% sky coverage for PTI.2008ApJS..176..276Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/176/276CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/393/183 : Catalogue of calibrator stars for LBSI (Borde+, 2002)J/A+A/433/1155 : 200m baseline interferometry calibrator stars (Merand+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/176/276https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/176/276http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/176/276https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/176/276https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/176/276http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/176/276GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/176/276/stars (Summary of photometry and SES fits for potential PTI calibrations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/176/276/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/176/276/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/176/276/stars?GETtext/xml+votable180.050000true1.415535655.70989780.0055555555555555566/8 116 129 140 183 188 309 340 349 375 377 429 463 472 474 706 744 770 826 934 953 1001 1020 1033 1035 1121 1167 1227 1247 1287 1430 1456 1512 1586 1603 1604 1610 1714 1719 1792 1842 1875 1923 1955 1963 1967 2027 2106 2169 2200 2225 2254 2317 2371 2464 2467 2493 2603 2650 2652 2690 2691 2723 2790 2818 2823 2852 2896 2921 2949 2990 3085 3095 3144 3242 3258 3313 3405 3640 3681 3714 3721 3780 4140 4224 4363 4419 4468 4506 4591 4661 4698 4724 4749 4808 4869 4886 4942 5009 5073 5074 5088 5137 5154 5304 5309 5311 5323 5339 5413 5423 5484 5522 5531 5718 5772 5777 5836 5873 5929 6052 6066 6153 6308 6339 6354 6523 6646 6672 6674 6693 6766 6825 6830 6926 6941 7239 7267 8219 8381 8402 8474 8475 8494 8496 8526 8534 8571 8580 8592 8602 8643 8717 8746 8748 8787 8814 8844 8869 8941 8969 8985 8995 9024 9036 9057 9105 9125 9165 9179 9212 9262 9281 9331 9350 9389 9476 9492 9642 9648 9662 9677 9759 9764 9801 10034 10371 10545 10552 10598 10632 10695 10741 10766 10804 10812 10814 10907 10926 11031 11314 11383 11444 11598 11633 11643 11676 11910 12108 12144 12238 12255 12388 12512 12561 12592 12634 12645 12659 12662 12695 12750 12755 12825 12827 12848 12890 12896 12899 12971 13138 13158 13166 13204 13205 13277 13296 13302 13308 13369 13379 13415 13419 13445 13474 13507 13557 13565 13611 13642 13682 13688 13709 13756 13850 13881 13915 13948 13953 13994 14015 14126 14144 14146 14180 14206 14209 14290 14342 14375 14459 14465 14490 14522 14523 14534 14539 14545 14573 14640 14641 14650 14662 14666 14688 14690 14693 14729 14764 14791 14851 14861 14988 15030 15144 15162 15170 15177 15260 15356 15383 15392 15620 15669 15883 15962 16020 16289 17723 17756 17820 17847 17918 18002 18004 18034 18101 18102 18103 18210 18234 18783 18804 19136 19277 19309 19345 19405 19519 19547 19745 19802 20005 20113 20118 20125 20127 20134 20145 20175 20298 20301 20304 20313 20322 20327 20328 21432 21484 21543 21696 21843 22013 22157 22180 22285 22330 22334 22511 22654 22790 22823 22841 22849 22979 22982 23096 23161 23201 23323 23375 23408 23426 23438 23502 23503 23523 23532 23537 23539 23544 23547 23575 23621 23661 23675 23773 23963 23974 23979 24013 24028 24029 24137 24144 24223 24268 24299 24451 24536 25588 25854 25973 26014 26078 26440 26450 26457 26465 26494 26521 26582 26770 26929 27006 27102 27374 27506 27735 27736 27740 27794 27954 27975 27979 28062 28122 28136 28137 28191 28208 28215 28274 28390 28446 28494 28664 29680 30114 30160 30220 30229 30289 30307 30344 30354 30416 30458 30471 30482 30576 30579 30660 30670 30673 30825 30878 30965 30989 31132 31284 31325 31374 31393 31472 31600 31664 31700 31730 31756 31776 31794 31976 32017 32091 32127 32205 32287 32296 32357 32384 32491 32575 32590 32610 32617 32694 32757 36723 36804 37882 38897 43115 45029 49060 49114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/176/276?format=asciiInfrareddefaultJ/ApJS/176/276/starsSummary of photometry and SES fits for potential PTI calibrationsrecnoRecord number assigned by the VizieR team.
