11. source comment
... The derived position here agrees with the position from recent ATCA observations, RA=15h 01m 34.74s, Dec=39 18 39.2" (Tasker, private communication) which found the source unresolved. Because of the relatively large position offset, the reality of the fainter component 0.12" to the west is somewhat in doubt. However, the ATCA centroid position is offset by 0.3" to the south-east of the VLBA position, suggesting that the faint component may be part of more extended structure. ...
