This is a double with separation of 430 mas From pls: A gravitational lens with an overall size of 2.2" (e.g. Katz, Moore & Hewitt 1997). Two of the four lensed components are in our field of view, separated by ~430 mas (Figure 4). See Porcas (1998) and Trotter, Winn & Hewitt (2000) for recent 5 GHz VLBI images of this system. The prelaunch model resolves, and matches the survey data. #--------------------------------------------------------------------------- # Section 2 : Pre-AIPS Checklist #--------------------------------------------------------------------------- {PI letter retrieved (yes/no)} : n {Data quality reports and plots retrieved?
