cds-question@unistra.frspectroscopyultraviolet-astronomyastronomical-object-identificationvisible-astronomyWide-band photometrystellar-spectral-typesparallaxStarCAT is a catalog of high resolution ultraviolet spectra of objects classified as "stars," recorded by Space Telescope Imaging Spectrograph (STIS) during its initial seven years of operations (1997-2004). StarCAT is based on 3184 echelle observations of 545 distinct targets, with a total exposure duration of 5.2Ms. For many of the objects, broad ultraviolet coverage has been achieved by splicing echellegrams taken in two or more FUV (1150-1700{AA}) and/or NUV (1600-3100{AA}) settings. In cases of multiple pointings on conspicuously variable sources, spectra were separated into independent epochs. Otherwise, different epochs were combined to enhance the signal-to-noise ratio (S/N). A post-facto correction to the "calstis" pipeline data sets compensated for subtle wavelength distortions identified in a previous study of the STIS calibration lamps. An internal "fluxing" procedure yielded coherent spectral energy distributions (SEDs) for objects with broadly overlapping wavelength coverage. The best StarCAT material achieves 300m/s internal velocity precision; absolute accuracy at the 1km/s level; photometric accuracy of order 4%; and relative flux precision several times better (limited mainly by knowledge of SEDs of UV standard stars). While StarCAT represents a milestone in the large-scale post-processing of STIS echellegrams, a number of potential improvements in the underlying "final" pipeline are identified.2010ApJS..187..149Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/187/149CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/39 : UV Bright Star Spectrophotometric Catalog (Jamar+, 1976)III/235 : Spectroscopically Identified White Dwarfs (McCook+, 2008)J/AJ/119/486 : HDF-S: STIS imaging (Gardner+, 2000)http://archive.stsci.edu/prepds/starcat : StarCAT home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/187/149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/187/149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/187/149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/187/149https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/187/149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/187/149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/187/149/starcat (Merged StarCAT sample: names and properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/187/149/starcat?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/187/149/starcat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/187/149/starcat?GETtext/xml+votable180.050000true1.51463.680.0055555555555555566/140 311 333 342 474 706 798 953 1024 1032 1042 1044 1060 1074 1111 1114 1115 1124 1168 1169 1170 1196 1198 1293 1504 1535 1539 1550 1554 1577 1805 1808 1875 1890 1965 2025 2248 2593 2619 2623 2909 3020 3053 3066 3118 3214 3245 3247 3256 3257 3314 3585 3601 3712 4322 4355 4376 4444 4468 4574 4594 4709 5413 5512 5609 6040 6108 6153 6219 6471 7075 7240 7252 7510 7610 7772 7779 7848 8068 8476 8547 8767 8790 9125 9476 9512 9680 9696 9733 9835 9847 10158 10337 10386 10476 10812 11126 11171 11176 11473 11605 11612 11673 11958 12271 12298 12337 12405 12500 12577 12644 12704 12768 12859 12865 12983 13255 13289 13480 13722 13729 13743 13995 14018 14062 14179 14197 14220 14226 14240 14249 14311 14443 14534 14545 14630 14632 14643 14797 14805 14810 14845 15376 15392 15478 15479 15562 15569 15580 15611 15631 15656 15657 15662 15663 15745 15748 15749 15768 15842 16115 16144 16234 16245 16394 16463 16734 16834 16886 17156 17420 17425 17492 17716 17754 17790 17918 18289 18346 18398 18817 18928 18978 19547 19827 19897 19970 20118 20178 20212 20328 20390 20460 20494 20701 20834 20915 21209 21215 21233 21432 21434 21438 21439 21530 21671 21696 21804 21833 21864 21951 22033 22180 22289 22300 22579 22616 22660 22751 22854 22859 22885 22941 23010 23191 23230 23339 23344 23360 23454 23489 23497 23518 23526 23538 23539 23540 23547 23548 23549 23557 23611 23621 23673 23704 23800 23945 23998 24048 24110 24139 24151 24195 24201 24300 24463 24513 24842 24862 24924 25008 25444 25585 25799 25988 25993 26025 26457 26963 27095 27402 27497 27578 27822 27975 28026 28134 28151 28259 28336 28494 28664 28673 28687 28696 28700 28772 28796 28891 28921 28959 29040 29138 29196 29207 29300 29600 29721 29897 30576 30709 30825 30878 31057 31072 31125 31132 31417 31622 31751 31757 32352 32473 32558 32619 32893 32958 33053 33067 33092 33094 33096 33112 33113 33122 33126 33127 33294 33295 33298 33304 33306 33317 33328 33795 33849 34054 34652 34823 34878 35517 35573 35768 35798 36043 36130 36564 36693 36697 36711 36942 36944 36959 37145 37186 37209 37216 37231 37232 37247 37323 37331 37332 37333 37334 37339 37763 37822 37871 37877 37893 37897 37900 37930 37963 38016 38024 38045 38072 38095 38110 38382 38449 38992 39085 39192 39240 39374 39539 39689 39693 39775 39803 39864 39931 40223 40716 40807 40892 41103 41270 41371 41390 41510 41528 41591 41598 41637 41646 41653 41655 41692 41696 41698 41763 41916 41917 41994 42076 42214 42268 42312 42331 42405 42417 42549 42609 42611 42640 42666 42671 42704 42740 42748 42791 42947 42994 43011 43023 43028 43033 43040 43041 43045 43062 43107 43227 43313 43677 43947 43992 44100 44281 44319 44508 44542 44575 44669 44707 44771 45105 45353 45472 45638 45821 45909 45984 46491 47100 47125 47147 47168 47244 47525 47536 48274 48501 48572 48663 48687 48824 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/187/149?format=asciiUVOpticaldefaultJ/ApJS/187/149/starcatMerged StarCAT sample: names and propertiesNotesNotesmeta.notecharnullablerecnoRecord number assigned by the VizieR team.
