Interferometer phase calibration sources - II.The region 0 deg<=DEC50 <=20 deg
(ctsy. Ian Browne 11/97; TeX to ASCII by H.Andernach 11/97)
abstract
We present a catalogue of 782 compact radio sources in the declination
range 0o < Delta(B1950) < +20o whose
positions have been measured to an rms accuracy of about 14~mas with
the VLA. These sources are primarily intended for use as phase
calibration sources for the Jodrell Bank MERLIN. However, they will
also be suitable as phase calibrators for the VLA and can be
considered as candidate phase calibrators for VLBI Networks.
description for tables 2 and 3:
Col 1. Source name derived from B1950 coordinates.
Col 2. Source name derived from J2000 coordinates.
Col 3. Right ascension (hour, min, sec) in J2000.
Col 4. Declination (deg, arcmin, arcsec) in J2000.
Col 5. Total flux density in mJy at 8.4~GHz.
Col 6. Peak flux density in mJy per beam at 8.4~GHz.
Col 7. Comments about the source, mainly regarding structure.
Terms have the following meaning:
- weak - weak;
- str - structure;
- ext - extension;
- sec - secondary component;
- pa - position angle in degrees with separation in arcsec;
- res - resolved;
- sli - slightly;
- dou - double;
- vlbi - quoted position is from the VLBI catalogues of Ma et al.
(1990) and Russell et al. (1991), with additional source
positions provided by Dr J.L. Russell;
- check - used to check absolute positional accuracy (see Section~4);
- image - map presented in this paper (see Figure~A1 and Table~A1
in Appendix A1).
