gavo@ari.uni-heidelberg.de+49 6221 54 1837starssurveysastrometryphotographic-photometry URAT1 is an observational catalog at a mean epoch between 2012.3 and 2014.6; ot covers the magnitude range 3 to 18.5 in R-band, with a positional precision of 5 to 40 mas. It covers most of the northern hemisphere and some areas down to -24.8° in declination. In the GAVO data center, we left out all columns originating from cross matches with other catalogs; on-the fly crossmatches can be done in our TAP service.2015AAS...22543301Zhttp://dc.g-vo.org/tableinfo/urat1.mainIsServedByGAVO Data Center TAP servicehttp://dc.g-vo.org/taphttps://dc.g-vo.org/tapNOFS, ArizonaCTIO, ChileUSNO Robotic Astrometric Telescope0/0-3 1/19,23,27,31 2/69,71,73,75,85-87,89-91,101-103,105-107,117-119,121-123 3/273,283,291,297-299,333-335,337-339,353,355,397-399,401-403,418-419,455,461-463,466-467,481-483,574-575,637-639,701-703,766-767 4/1083,1086-1087,1091,1101,1127,1130-1131,1158-1159,1185-1187,1311,1325,1327,1331,1347,1411,1417-1419,1567,1583,1587,1603,1667,1669-1671,1811,1814-1815,1839,1843,1859,1861-1863,1923,2287,2291,2293-2295,2527,2543,2547,2783,2799,2803,3055,3059 5/4326-4327,4329-4331,4338-4339,4342-4343,4359,4363,4388-4389,4401,4412-4413,4415,4501-4503,4505,4507,4519,4623,4627,4629-4631,4653-4655,4737-4739,5239,5243,5277-5279,5307,5319,5322-5323,5383,5387,5639,5665-5667,6261-6263,6265-6267,6327,6341-6343,6345,6347,6405-6407,6411,6663,6667,6675,7237-7239,7243,7248,7250-7251,7254,7268-7269,7271,7349-7351,7353-7355,7365-7367,7369-7371,7431,7434-7435,7441-7443,7685-7687,7689-7691,9085-9087,9143,9147,9159,9163,9169-9171,10103,10107,10167,10171,10183,10187,11127,11131,11189-11191,11194-11195,11207,11209-11211,12213-12215,12217,12219,12230-12231,12233-12235,12248,12250-12251,12253-12255 6/17151,17295,17298-17300,17302-17303,17314-17315,17346-17348,17350-17351,17362,17366-17367,17429-17431,17433-17435,17445-17447,17449,17451,17540-17541,17543,17560-17561,17563-17566,17600-17602,17613,17615,17636-17637,17639,17656-17657,17659,17997-17999,18002-18003,18017-18019,18025,18027,18056,18058-18059,18071,18075,18487,18507,18513,18515,18581,18590-18591,18605,18607,18609,18611,18945,18947,20949-20951,20953-20955,20965-20967,20969-20971,21103,21107,21188-21189,21191,21221-21223,21225-21227,21269-21271,21273-21275,21282,21285-21287,21525-21527,21529-21531,21543,21547,22549-22551,22553-22555,22565-22567,22573-22575,22657-22659,24959,25023,25039,25043,25059,25303,25307,25319,25324-25325,25327,25359,25363,25379,25387,25619,25637,25639,25642-25643,26649-26651,26661-26663,26665-26667,26695,26697-26699,28943,28947,28965-28967,28969,28971,28996,28998-28999,29010,29022,29060-29061,29063,29080-29081,29083,29109,29119,29311,29375,29391,29395,29411,29455,29459,29475,29723,29735,29761-29763,30735,30739,30755,36317-36319,36333-36335,36337-36339,36567,36569-36571,36581-36583,36585-36587,36635,36647,36651,36673-36675,40405-40407,40409,40411,40423,40426-40427,40661-40663,40665-40667,40677-40679,40681-40683,40725-40727,40729-40731,40741-40743,40745-40747,44415,44501-44503,44505-44507,44517-44519,44521-44523,44671,44735,44751,44755,44773-44775,44823,44827,44835,48063,48106-48107,48767,48847,48851,48867,48911,48915,48918-48919,48931,48970,48989,48991,48998,49009-4901155927 570222.879e-19 3.679e-19Opticalurat1 URAT1 is an observational catalog at a mean epoch between 2012.3 and 2014.6; ot covers the magnitude range 3 to 18.5 in R-band, with a positional precision of 5 to 40 mas.
