. Comment on J1242-0446 . No detection: an extended double-lobe radio galaxy, not detected at 2.3 GHz by Preston et al. (1985). Mantovani et al. (1997) did not detect a core even with the VLA at 8.4 and 15 GHz. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J1239-1023 . No image is shown by Dallacasa et al. (1998) as they did not find the VLBI structure at 2.3 and 8.4 GHz prominent, just dominated by a compact region barely resolved in position angle about -45 . In our case the source is well resolved, with a jet pointing to the W-NW direction, in agreement with what is seen in the images at 2.3 and 8.4 GHz from the VLBA Calibrators database.

. Comment on J1232-0224 . Hooimeyer et al (1992a) detected the source on the Green Bank-Owens Valley baseline at 5 GHz (correlated flux density 180 mJy) and found that the nuclear emission was probably diffuse. The jet position angle in a 1.4 GHz VLA image (Hintzen, Ulvestad & Owen 1983) is similar to that in our VLBA image. Our image is consistent with the images at 2.3 and 8.4 GHz from the VLBA Calibrators database. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J1225+1253 . Early 2.3 GHz VLBI observations (Jones, Terzian & Sramek 1981) indicate an elongated source structure in the N-S direction, in agreement with our image. Giovannini, Feretti & Comoretto (1990) measured a 180 mJy correlated flux density at 1.6 GHz on the shortest VLBI baselines. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J1146-3328 . The derived position here is about 20" from that of the PMN survey position (Griffith & Wright 1993). The source is only detected on the shorter baselines and is probably resolved, although some smearing may be caused by the large position offset. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J1130-1449 . There are two dominant components in our image. Comparison with the 15 GHz image of Kellermann et al. (1998) reveals that the western component is brighter at the higher frequency, indicating that the brighter (eastern) component in our image may have a steep spectrum. VLBApls home page .

. Comment on J1058+1951 . The source structure is elongated in the N-S direction. The 15 GHz image by Kellermann et al. (1998) shows a 4 mas jet to the N. The 5 GHz image by Hooimeyer et al. (1992b) has extensions to both N and S. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J1018-3144 . Resolved: There is 0.5 Jy of correlated flux density at the shortest baselines. The position is accurate, so the source is resolved. It was also not detected at 2.3 GHz by Preston et al. (1985). See Figure 3. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J0957+5522 . A 5 GHz MERLIN image (Xu et al. 1995) shows a 200 mas jet pointing to the W, and indicates that the core is elongated to the SW. Our map of the core region indicates a bending jet from mas to arcsecond angular scales. VLBApls home page . Last modified: 16 Oct 2000

. Comment on J0758+3747 . Our image is in agreement with that of Polatidis et al. (1995) and Xu et al. (1995) at 1.6 and 5 GHz.
