cds-question@unistra.frsurveysx-ray-sourcesThe Chandra Transmission Grating Data Archive and Catalog (TGCat) provides easy access to analysis-ready products, specifically, high-resolution X-ray count spectra and their corresponding calibrations. The web interface makes it easy to find observations of a particular object, type of object, or type of observation; to quickly assess the quality and potential usefulness of the spectra from pre-computed summary plots; or to customize a view with an interactive plotter, optionally combining spectra over multiple orders or observations. Data and responses can be downloaded as a package or as individual files, and the query results themselves can be retrieved as ASCII or Virtual Observatory tables. Portable reprocessing scripts used to create the archive and which use the Chandra X-ray Center's (CXC's) software and other publicly available software are also available, facilitating standard or customized reprocessing from Level 1 CXC archival data to spectra and responses with minimal user interaction.2011AJ....141..129Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/129CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/129https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/129http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/129https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/129https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/129http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/129GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/141/129/table6 (Observation catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/129/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/129/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/129/table6?GETtext/xml+votable180.050000true2.0756851.387970.0055555555555555566/27 311 557 845 1115 1169 1196 1504 1558 1694 1701 1704 2273 2809 3030 3044 3309 3431 3633 4215 4439 4444 4653 4790 5091 5377 5423 5609 5941 6021 6241 6340 7606 7610 7636 7642 7752 7763 7799 7869 7969 8906 8922 9194 9401 9442 9512 10255 10265 10386 10481 10605 10912 10927 10977 11290 11339 11388 11690 11856 11898 12405 12859 13110 13414 13743 13778 13797 13875 13947 14018 14285 14401 14443 14632 14670 14692 14788 14858 15090 15135 15351 15478 15934 16144 16184 16186 16447 16671 16834 17075 17716 17727 17754 17989 18030 18683 18817 19283 19864 19897 19970 20071 20099 20102 20178 20286 20460 20940 21401 21438 21439 21450 22300 22485 22628 22854 22862 22884 23134 23191 23323 23637 23652 23717 23830 24072 24185 24451 24951 25113 25452 25659 25675 25907 26037 26131 26148 26292 27428 27765 27767 27862 28019 28151 28356 28517 28690 28701 28705 28707 28744 28746 28751 28772 28805 28808 28817 28827 28830 28831 28835 28877 28879 28890 28896 28925 28971 29002 29072 29114 29116 29162 29204 29306 29398 29463 29514 29664 29870 29923 30029 30244 30262 30298 30299 30315 30362 30439 30502 30506 30543 30580 30598 30607 30622 30818 31158 31774 33034 33055 33085 33088 33094 33097 33106 33113 33116 33120 33124 33318 33328 33403 33716 33801 34242 34535 34881 35150 35623 36130 36526 36697 36775 36786 37306 37366 37475 37732 37925 37930 38016 38045 38095 38151 38191 38268 38347 38382 38528 38653 39085 39118 39216 39235 39327 39825 39853 39907 39937 40018 40131 40249 40615 40777 41279 41295 41399 41446 41472 41530 41586 41591 41647 41670 41697 41802 41809 41814 42140 42159 42189 42196 42210 42213 42215 42229 42315 42384 42393 42397 42417 42464 42467 42704 42948 42981 43014 43020 43035 43233 43262 43321 43523 43626 43677 43806 43853 43877 43947 44381 46615 47014 47016 47047 47154 47287 47496 47805 47824 48034 48163 48274 48804 48905 49001 49042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/141/129?format=asciiX-raydefaultJ/AJ/141/129/table6Observation catalogExpExposure timestime.duration;obs.exposuredoublerecnoRecord number assigned by the VizieR team.
