. Comment on J1554-2704 . The image here is in good agreement with a 2.3 GHz image from the VLBA Calibrators database. Lovell (in preparation) gives a position of RA=15h 54m 02.47s, Dec=-27 04 40.2", in good agreement with that derived from these observations. The correlating position was 9" offset, but should not affect the quality of the image. VLBApls home page . Last modified: 16 Oct 2000
