Congratulations, guys !
This is very close to the "2 %" result quoted in july for runs 700-800.
Please see attach (2 sectors are shown). To me it confirms that indeed
- once all corrections and recrunch are made, which takes a lot of work
and time - we get consistent reconstruction results for inbending and
outbending field. This is an important result for libBlast.
There is - of course - a lot more to be done, and maybe new corrections
have to be discovered, in terms for instance of recon efficiency and other
L,R differences Slowly but surely we should get over these issues
(that have been discussed many times).
