. Comment on J1842+7946 . Comparing the brightnesses of the two main features seen in our 5 GHz image with higher frequency VLBI images available in the literature (at 8.4 GHz from the USNO database and at 15 GHz by Kellermann et al. (1998)), one can conclude that the NW component has a steeper spectrum since the SE one becomes relatively stronger as the observing frequency increases. VLBApls home page .

... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...
