Hi Hiro, Concerning the offsets, there is a calibration to do each time a time calibration is done for the BB. We already know that it comes with fluctuation in the slewing fit tails. So, if you get a vertex, given a certain time calibration, but use the vertex offset resulting from a calibration done before or after, you will get a small offset. That's why I told the guys who filled the DB that each time they commit a BB calibration, they MUST also provide the vertex offset calibration corresponding to the BB calibration committed. And I know that at least Claus is doing it now. So it's coming along...
