A little difficulty steering through the south. Noted the beam was a vertical stripe by the time we got to the 2L18 viewer. Grabbed the 1R V. betatron quads to round up the beam on the viewer.

Good injector setup to ILD. Good colinearity and ~99% transmission for 85uA C beam. Wien46.5 total. Good match. Ready for moving to North Linac. Save #27304 by kazimi

I checked the injector setup it is still very good. I did some improvement to colinearity of the beams and improved the transmission through A3 (Fig. 8). At the end we checked the match and it was also good (linked).
I think the beams are good for NL. We could improve the beam qualities by working on Lasers B and D tails. Figure 5 shows the tails for B and D in the chopper when Prebuncher is off, C is fine.
