! Source file for single dish Pointing of VLBA antennas. ! Useful both for systems tests and for reference pointing. ! ! ***** DO NOT USE FOR VLBI **** ! (Many of the positions are not good enough) ! ! ! There are three main sections containing sources of different ! types. They are: ! H2O masers (22 GHz) ! SiO masers (43 and 86 GHz) ! Continuum VLBI sources ! ! ! Note on CALCODES: ! 'L' On and off line frequencies will be used for pointing ! solutions for pointing analysis but not for reference ! pointing???. ! 'C' ??? ! 'B' ??? ! ! 17 April 2001 - CALCODE=L set for many SiO masers. RCW. ! ! ---------------- 7 mm SiO masers -------------------- ! Adapted from Vivek Dhawan's pointing_sources.dat on 5 Aug 2000 by RCW ! Prior to that date, there were 2 previous sets with different names for ! some of the same sources. The names have been added here now that the ! multiple name option is available. This will help prevent old master schedules ! from failing. It is recommended that users use the name that starts ! with "P-" to obviously distinguish the source from VLBI target sources. ! The older lists were from Vivek on April 1993 and 9 July 1997. Some of ! those sources are retained below for reasons explained in individual ! comments. ! SiO- MASERS: v=1 J=1-->0 43.122GHz. ! These sources are intended for use for reference pointing. ! Spectra are available on the SEST web page if necessary. ! ! For questions: Contact Vivek Dhawan, vdhawan@nrao.edu. ! Set all to use on-off frequency data for pointing analysis pointing ! fits. This is not used for reference pointing???. calcode='L' source='P-YCas' CALCODE = 'L' RA=00:00:47.0 DEC=55:24:06 epoch=b1950 vel=48.6,48.6 remarks='Jewell' / source='P-IRC+10011', 'P-IRC+10' CALCODE = 'L' RA=01:03:48.1 DEC=12:19:51 epoch=b1950 vel=7.1, 7.1 remarks='Jewell.' / source='P-OCeti', 'OCeti' CALCODE = 'L' RA=02:19:20.793 DEC=-02:58:37.0 epoch=j2000 vel=45.0, 45.0 remarks='Baudry position, SEST spectrum' / source='P-SPer' CALCODE = 'L' RA=02:22:51.713 DEC=58:35:11.5 epoch=j2000 vel=-40., -40. remarks='Baudry' / source='P-IkTau','SiO-IkTau','IkTau' CALCODE = 'L' RA=03:53:28.71 DEC=11:24:22.6 epoch=j2000 vel=35.,35. remarks=' SEST pos & vel.' / source='P-IRC+50137' CALCODE = 'L' RA=05:07:19.7 DEC=52:48:54 epoch=b1950 vel=2.7, 2.7 remarks='Jewell.' / source='P-SOri' CALCODE = 'L' RA=05:26:32.7 DEC=-04:43:52 epoch=b1950 vel=12.9, 12.9 remarks='Jewell. weak.' / source='P-TxCam','SiO-TxCam', 'TxCam' CALCODE = 'L' RA=05:00:51.127 DEC=56:10:53.98 epoch=j2000 vel=7.5, 7.5 remarks='Baudry pos.' / source='P-Orinew2', 'SiO-OriIRC2', 'OriIRC2' CALCODE = 'L' RA=05:35:14.505 DEC=-05:22:30.45 epoch=j2000 vel=-5,-5 remarks='3mm test peakup @1MHz BW' / source='P-UOri','SiO-UOri' CALCODE = 'L' RA=05:55:49.171 DEC=20:10:30.34 epoch=j2000 vel=-40.5, -40.5 remarks=' baudry pos&vel; weak.' / source='P-VCam', 'SiO-VCam' CALCODE = 'L' RA=05:55:57.7 DEC=74:30:23 epoch=b1950 vel=6.5, 6.5 / source='P-IRC+60169' CALCODE = 'L' RA=06:30:00.6 DEC=60:58:50 epoch=b1950 vel=-23.9, -23.9 remarks='Jewell.' / source='P-GXMon' CALCODE = 'L' RA=06:52:46.93 DEC=08:25:21.1 epoch=j2000 vel=-10, -10 remarks='sest' / source='P-VYCMa', 'SiO-VYCMa', 'VYCMaSiO' CALCODE = 'L' RA=07:22:58.27 DEC=-25:46:03.4 epoch=j2000 vel=15., 15. remarks='sest BW=4MHz' / source='P-VYCMx1' CALCODE = 'L' RA=07:22:58.27 DEC=-25:46:03.4 epoch=j2000 vel=10., 10. remarks='sest BW=2MHz' / source='P-VYCMx2' CALCODE = 'L' RA=07:22:58.27 DEC=-25:46:03.4 epoch=j2000 vel=22., 22. remarks='sest BW=1MHz' / source='P-RCnc' CALCODE = 'L' RA=08:16:33.826 DEC=11:43:34.60 epoch=j2000 vel=14., 14. remarks='Baudry pos, sest vel' / source='P-IRC-20197' CALCODE = 'L' RA=09:42:56.6 DEC=-21:47:54 epoch=b1950 vel=42.0, 42.0 remarks='Jewell.' / source='P-RLMi', 'SiO-RLMi' CALCODE = 'L' RA=09:45:34.10 DEC=34:30:43.9 epoch=j2000 vel=2., 2. remarks='sest' / source='P-RLeo', 'SiO-RLeo', 'RLeo' CALCODE = 'L' RA=09:47:33.490 DEC=11:25:43.99 epoch=j2000 vel=3.0,3.0 remarks='baudry pos, sest vel.' / source='P-RCrt' CALCODE = 'L' RA=11:00:33.98 DEC=-18:19:28.5 epoch=j2000 vel=11., 11. remarks='sest' / source='P-RHya' CALCODE = 'L' RA=13:49:58.5 DEC=-23:01:25 epoch=b1950 vel=-11.3, -11.3 remarks='Jewell.' / source='P-RXBoo' CALCODE = 'L' RA=14:24:11.609 DEC=25:42:13.73 epoch=j2000 vel=4, 4 remarks=' Baudry pos, sest vel' / source='P-SCrB', 'SiO-SCrB' CALCODE = 'L' RA=15:21:23.94 DEC=31:22:03.3 epoch=j2000 vel=1.8, 1.8 remarks=' sest pos & vel' / source='P-WXSer' CALCODE = 'L' RA=15:25:32.0 DEC=19:44:13 epoch=b1950 vel=6.8, 6.8 remarks='Jewell.' / source='P-RUHer' CALCODE = 'L' RA=16:08:08.0 DEC=25:12:00 epoch=j2000 vel=-13.5, -13.5 remarks='baudry' / source='P-UHer', 'SiO-UHer' CALCODE = 'L' RA=16:25:47.52 DEC=18:53:32.8 epoch=j2000 vel=-14., -14. / source='P-OH2.6-0.4' CALCODE = 'L' RA=17:50:10.9 DEC=-26:56:00. epoch=b1950 vel=-3.9, -3.9 remarks='Jewell.' / source='P-AHSco' CALCODE = 'L' RA=17:11:16.98 DEC=-32:19:31.2 epoch=j2000 vel=-7, -7 remarks='sest.' / source='P-V2108oph' CALCODE = 'L' RA=17:14:19.37 DEC=08:56:02.5 epoch=j2000 vel=13, 13 remarks='sest.' / source='P-VXSgr', 'SiO-VXSgr', 'VXSgrSiO' CALCODE = 'L' RA=18:08:04.062 DEC=-22:13:26.1 epoch=j2000 vel=5.,5. remarks=' baudry pos, sest vel 2MHz BW' / source='P-GYAql', 'SiO-GYAql' CALCODE = 'L' RA=19:50:06.35 DEC=-07:36:52.8 epoch=j2000 vel=30., 30. remarks=' sest' / source='P-RAql' CALCODE = 'L' RA=19:06:22.19 DEC=08:13:47.4 epoch=j2000 vel=47, 47 remarks=' sest.' / source='P-RTAql' CALCODE = 'L' RA=19:38:01.60 DEC=11:43:18.5 epoch=j2000 vel=-29.7, -29.7 remarks='sest' / source='P-ChiCyg', 'SiO-ChiCyg', 'ChiCyg' CALCODE = 'L' RA=19:50:33.9 DEC=32:54:51.3 epoch=j2000 vel=10.,10. remarks=' sest + old avgd.' / source='P-RRAql' CALCODE = 'L' RA=19:57:36.16 DEC=-01:53:10.5 epoch=j2000 vel=26.9, 26.9 remarks='sest' / source='P-NMLCyg' CALCODE = 'L' RA=20:46:25.532 DEC=40:06:59.35 epoch=j2000 vel=-5, -5 remarks='baudry' / source='P-mucep', 'SiO-mucep', 'mucep' CALCODE = 'L' RA=21:43:30.446 DEC=58:46:48.4 epoch=j2000 vel=26.0,26.0 remarks='Baudry' / source='P-RPeg' CALCODE = 'L' RA=23:06:39.157 DEC=10:32:36.07 epoch=j2000 vel=20., 20. remarks='Baudry + sest' / source='P-RAqr', 'SiO-RAqr', 'RAqr' CALCODE = 'L' RA=23:43:49.44 DEC=-15:17:04.1 epoch=j2000 vel=-22.,-22. remarks=' sest' / !
