Old matrices
The following are the matrices that we used during the online analysis of the experiment:
[1] LHRS default matrix - I cannot find this file. Might be able to retrieve it from github, but it would only be here for legacy reasons.
Optimization steps
LHRS
The following is the LHRS matrix optimized by GMp
The following is an optimization that Shujie did on the GMp LHRS matrix [3] using the standard procedure for optimizing the angles and the sieve runs taken during MARATHON
[4] LHRS re-optimization by Shujie
RHRS
The following is the RHRS matrix optimized by GMp
Current (optimized) matrices
LHRS
Replaced in matrix [4] the line:
D 1 0 0 -6.863500E-02 2.633700E-01 1.096600E-02 -7.253300E-02
with:
D 1 0 0 4.932426E-03 2.633700E-01 1.096600E-02 -7.253300E-02
This is the coefficient that relates delta with theta (xptar) fp linearly. We did this to get rid of a slope we saw in Emiss vs. xptar.
RHRS
Replaced in matrix [5] the line:
D 0 0 0 1.816209E-03 8.382911E-02 7.297953E-03 3.822568E-03 1.149510E-02
with:
D 0 0 0 0.000000E+00 8.382911E-02 7.297953E-03 3.822568E-03 1.149510E-02
and added the following two lines:
T 0 0 0 -2.940000E-03
P 0 0 0 -1.567257E-03
