cds-question@unistra.frsurveysradio-continuum-emissionradio-sourcesWe present a catalog of compact sources of radio emission at 1420MHz in the northern Galactic plane from the Canadian Galactic Plane Survey. The catalog contains 72758 compact sources with an angular size less than 3' within the Galactic longitude range 52{deg}<l<192{deg} down to a 5{sigma} detection level of ~1.2mJy. Linear polarization properties are included for 12368 sources with signals greater than 4{sigma}_QU_ in the Canadian Galactic Plane Survey (CGPS) Stokes Q and U images at the position of the total intensity peak. We compare CGPS flux densities with cataloged flux densities in the Northern VLA Sky Survey catalog for 10897 isolated unresolved sources with CGPS flux density greater than 4mJy to search for sources that show variable flux density on timescales of several years. We identify 146 candidate variables that exhibit high fractional variations between the two surveys. In addition, we identify 13 candidate transient sources that have CGPS flux density above 10mJy but are not detected in the Northern VLA Sky Survey.2017AJ....153..113Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/113CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/128 : Log of CGPS exposures (Taylor+, 2003-)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/ApJ/702/1230 : Rotation measure image of the sky (Taylor+, 2009)J/ApJS/145/213 : Rotation measures of compact sources in CGPS (Brown+, 2003)www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/en/cgps : Canadian Galactic Plane Surveyhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/153/113https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/153/113http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/153/113https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/153/113https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/153/113http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/153/113GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/153/113/table2 (Canadian Galactic Plane Survey (CGPS) 1420MHz source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/153/113/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/153/113/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/153/113/table2?GETtext/xml+votable180.050000true0.0050861.139390.0055555555555555563/51 225 228 229 240 241 244 246 380 4/81 83 84 86 89 91 111 112 113 114 120 122 191 197 199 208 225 227 228 232 233 810 890 891 893 894 895 896 897 980 982 988 990 997 1008 1009 1012 1498 1499 1529 1531 1534 2005 5/321 323 329 331 353 355 361 363 368 370 376 415 437 439 460 461 462 484 486 757 758 759 761 762 763 787 793 794 795 813 815 840 842 864 899 905 906 907 916 918 920 921 922 936 937 938 940 944 3246 3247 3258 3259 3262 3263 3499 3502 3503 3514 3515 3517 3518 3519 3551 3559 3569 3570 3592 3593 3596 3597 3599 3680 3681 3684 3685 3696 3697 3700 3893 3895 3901 3903 3924 3925 3926 3932 3934 3956 3958 3964 3966 5951 6037 6098 6104 6106 6112 6113 6115 6121 6123 6128 6130 6131 7677 7679 8029 6/1281 1283 1289 1291 1313 1362 1368 1370 1411 1417 1419 1441 1443 1449 1451 1476 1478 1484 1512 1513 1514 1631 1653 1655 1747 1753 1755 1775 1852 1854 1856 1858 1864 1940 1942 1968 1969 1970 1976 1978 2812 2941 2942 2943 3005 3006 3007 3021 3022 3023 3025 3026 3027 3041 3042 3043 3141 3142 3143 3169 3171 3223 3229 3230 3231 3251 3257 3258 3259 3364 3366 3372 3464 3466 3488 3589 3591 3595 3617 3618 3619 3668 3670 3692 3693 3694 3696 3698 3756 3757 3758 3764 3768 3784 12938 12939 12942 12976 12978 12979 12982 12983 13026 13027 13226 13227 13230 13231 13242 13243 13246 13290 13291 13294 13295 13306 13307 13310 13311 13994 13995 14050 14051 14054 14055 14065 14066 14067 14202 14203 14222 14223 14234 14235 14274 14275 14284 14286 14287 14377 14380 14381 14392 14393 14395 14529 14532 14533 14544 14545 14548 14549 14551 14804 14805 14806 15488 15489 15492 15493 15504 15505 15508 15509 15552 15601 15603 15609 15611 15708 15709 15710 15732 15734 15740 15742 15828 15830 15836 15973 15984 15985 15988 15989 16160 16161 16164 16165 16176 16177 16180 16181 16208 16209 16210 16216 16217 16218 16224 16225 16228 16229 16240 23797 23799 23801 23951 23962 23963 23966 24042 24156 24157 24159 24181 24183 24384 24386 24428 24430 24456 24457 24459 24481 24483 24489 24491 24516 24518 30687 30707 30713 30715 32113https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/153/113?format=asciiRadiodefaultJ/AJ/153/113/table2Canadian Galactic Plane Survey (CGPS) 1420MHz source catalogrecnoRecord number assigned by the VizieR team.
