Abstract
Kajs extraction had digicor -1 -- nor ACCOR I think (missing SN6?). So I redid. However I used Kajs ANTAB values.

"GOT extraction from v053b (SC, NL, HN, and BR + HALCA). J0626+8202 is a z= 1.430 QSO. The image shows a core and a slightly curved jet. Noise level is rather high despite the use of gscale and the model fits rather well to the closure phases."
