cds-question@unistra.frgalaxy-planesmilky-way-galaxycataclysmic-variable-starsvisible-astronomyh-alpha-photometryaccretionWe present a catalogue of point-like H{alpha}-excess sources in the Northern Galactic Plane. Our catalogue is created using a new technique that leverages astrometric and photometric information from Gaia to select H{alpha}-bright outliers in the INT Photometric H{alpha} Survey of the Northern Galactic Plane (IPHAS), across the colour-absolute magnitude diagram. To mitigate the selection biases due to stellar population mixing and to extinction, the investigated objects are first partitioned with respect to their positions in the Gaia colour-absolute magnitude space, and in the Galactic coordinates space, respectively. The selection is then performed on both partition types independently. Two significance parameters are assigned to each target, one for each partition type. These represent a quantitative degree of confidence that the given source is a reliable H{alpha}-excess candidate, with reference to the other objects in the corresponding partition. Our catalogue provides two flags for each source, both indicating the significance level of the H{alpha}-excess. By analysing their intensity in the H{alpha} narrow band, 28496 objects out of 7474835 are identified as H{alpha}-excess candidates with a significance higher than 3. The completeness fraction of the H{alpha} outliers selection is between 3% and 5%. The suggested 5sigma conservative cut yields a purity fraction of 81.9%.2021MNRAS.505.1135Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/505/1135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)IV/36 : Gaia-IPHAS/KIS Value-Added Catalogues (Scaringi+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/505/1135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/505/1135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/505/1135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/505/1135https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/505/1135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/505/1135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/505/1135/haexlit (Light version of the Gaia/IPHAS catalogue of the Ha-excess sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/1135/haexlit?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/1135/haexlit?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/1135/haexlit?GETtext/xml+votable180.050000true359.999983943445962.2720950179460.005555555555555556Cone search capability for table J/MNRAS/505/1135/haexfull (Full version of the Gaia/IPHAS catalogue of the H{alpha}-excess sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/505/1135/haexfull?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/505/1135/haexfull?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/505/1135/haexfull?GETtext/xml+votable180.050000true43.92172528025664.22629747971920.0055555555555555563/20 22 223 225 228-229 240 347 380 382 478 4/84 109 111-114 120 122 189-191 197-199 203-206 208 225-228 232-233 810-811 814 875 878-879 890-891 896-897 964-966 976-977 980 1379 1382 1385 1476-1477 1479 1485 1487 1490 1496 1498 1534 1894-1895 1897 1900-1901 1916 1918-1919 2005 5/344-346 368 370 376 407 413 415 443 460 462 484 486 733 735 750-751 755 785-787 805 807 828-830 840 842 897-899 916 920-922 936-938 940 3234-3235 3238 3260 3262-3263 3306-3307 3310-3311 3322-3323 3326-3327 3498-3499 3511 3547 3549-3551 3554-3555 3557-3559 3592-3593 3596-3597 3599 3680-3681 3684-3685 3696 3868-3870 3912-3913 3916-3917 3924-3925 3928 5526 5532 5534 5549 5551 5608 5610 5912-5913 5915 5937 5939 5952 5954-5955 5966 5988 5990 5996 5998-5999 6036-6037 6039 6045 6047 6069 6098 6104 6106 6128 6130 7557 7559 7565-7567 7570-7571 7574 7609 7612-7613 7615 7624 7626-7627 7630-7631 7668 7670-7671 8004-8005 8016-8017 8019 6/1109 1111 1117 1119 1141 1237 1269 1271 1277 1279 1388-1390 1476 1478 1512 1514 1621-1623 1649 1651 1657-1659 1741 1743 1765-1767 1771 1844-1846 1852 1854 1856 1858 1968 1970 1976 2911 2937-2939 2991 2997-2999 3013-3015 3017-3019 3127 3133-3135 3137 3139 3219 3225-3227 3239 3245-3247 3324-3326 3364 3456-3458 3464 3466 3585 3587 3668 3672-3674 3692-3694 3696 3756-3758 3764 3776-3778 12930-12931 12958-12959 13002 13044 13046-13047 13218-13219 13222-13223 13234-13235 13238-13239 13282-13283 13286-13287 13298-13299 13302-13303 13986-13987 13989-13991 14026-14027 14030-14031 14041-14043 14143 14175 14186-14187 14193-14195 14211 14214-14215 14225-14227 14381 14392-14393 14532-14533 14544-14545 14548-14549 14551 14788-14790 14800-14802 14804-14805 15484-15486 15488-15489 15492-15493 15504-15505 15656-15657 15660-15661 15672-15673 15704-15706 15708-15709 15716-15717 22047 22055 22061 22063 22090-22091 22094-22095 22132 22134 22140 22142-22143 22193 22195 22402 22408 22410 22446 23572-23573 23575 23581 23657 23659 23745 23781 23783 23789 23791 23812 23814-23815 23856 23858 23964 23966 23988 23990-23991 24153 24155 24177 24179 24284-24285 24287 24309 24311 24317 24319 24384 24386 24430 24516 24518 24524 24526-24527 30233 30235 30257 30259 30272 30274-30275 30278-30279 30302-30303 30389 30432-30433 30457 30500 30502-30503 30514-30515 30570-30571 30574 30678-30679 32001 32004-32005 32029 32072-32073 32075 32112-32113 32116-32117 32119https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/505/1135?format=asciiOpticaldefaultJ/MNRAS/505/1135/haexlitLight version of the Gaia/IPHAS catalogue of the Ha-excess sourcesrecnoRecord number assigned by the VizieR team.
