(1981MNRAS.197..865W) and McHardy et al. (1981MNRAS.197..893M). ARIEL 5 scanned the sky for 5.5yrs in the energy bands 2-18 keV with a time resolution of one orbit (100min approximately). The fields in the catalog list source name and up to three alternative names; the error box center and corners in decimal degrees; average, minimum, and maximum flux and their error; a variability code; identification; and comments.</description><source format="bibcode">1981MNRAS.197..865W</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/IX/16</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/IX/2">IX/2 : Second Ariel X-Ray Catalogue (2A) (Cooke+ 1978)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/IX/4">IX/4 : Fourth UHURU Catalogue (4U) (Forman+ 1978)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=IX/16</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=IX/16</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=IX/16</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=IX/16</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=IX/16</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=IX/16</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table IX/16/3A (Complete 3A catalogue: low-latitude sources (I) and high-latitude sources (II))</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/IX/16/3A?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/IX/16/3A?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/IX/16/3A?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>6.2999</ra><dec>64.1568</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/56 87 206 620 839 1196 1263 1405 1466 1701 1716 2251 2389 2572 2623 3030 3044 3063 3089 3309 3633 3729 3819 4439 5423 5844 6751 6887 6976 7551 7606 8220 8268 8520 8922 9032 9354 9468 9504 9512 9613 10217 10312 10379 10475 10604 10710 10847 10912 11807 11898 12121 12405 13875 14018 14056 14251 14285 14317 14336 14410 14452 14632 14647 14692 14744 15090 15112 15370 15410 15481 15639 16296 16435 16511 16543 16706 16900 17074 17237 18524 18579 18683 18820 19282 20021 20286 20492 20618 21439 21448 21643 21690 22159 22246 22464 22577 23190 23322 23451 23652 23821 23967 23995 24185 24291 24381 24451 24943 25220 25391 25907 26148 26188 26292 27765 28249 28470 28517 28705 28723 28751 28798 28808 28825 28879 28896 28925 28973 29114 29204 29220 29234 29306 29463 29514 29533 29795 29870 29923 30184 30262 30298 30299 30317 30362 30439 30506 30580 30598 30618 30646 30753 31537 32483 32951 33049 33094 33113 33235 33294 33298 33317 33378 33628 33713 33795 34242 34443 34615 34881 35274 35520 35623 36234 36297 37207 37306 37377 37732 37863 37906 37925 38016 38028 38169 38263 38653 38704 38853 39077 39235 39266 39886 39937 40013 40432 40615 40809 41078 41279 41326 41399 41446 41530 41596 41662 41679 41699 41748 41758 41760 41802 41823 41873 42140 42196 42210 42215 42229 42315 42384 42434 42467 42487 42841 43020 43034 43035 43262 43365 43626 43836 43849 43877 43947 45542 45984 46442 46620 46860 46987 47014 47064 47169 47349 47805 48034 49042</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/IX/16?format=ascii</footprint><waveband>X-ray</waveband></coverage><tableset><schema><name>default</name><table><name>IX/16/refs</name><description>References</description><column><name>Ref</name><description>Reference code</description><ucd>meta.note</ucd><dataType xsi:type="vs:VOTableType" arraysize="3*">char</dataType></column><column><name>recno</name><description>Record number assigned by the VizieR team.
