First a pointing --> set pointing 1.4 -16.9 (really weird profiles, the reference pixels seems too far away from the center...) |

The pointing correction is large because the focus is still not good (elliptical beams) so we do a focus session again --> focus along the Z-axis direction --> set focus -0.5 |
