I have not studied these so closely, but Colin has data on many ops. I just blindly ran reconfit on these to get a number for Lorenzo. Kostas, if it's easy enough for you to run with a new input, then you should take a look at the same momentum with whatever
number of evecs and configs Colin used on the larger basis. The adat file is found at</div>

<div class="x_x_PlainText">Hi everybody,<br>
<br>
I finally resolved the issue I had. My ordering of the operators caused me to compare the ground state principal correlator effective mass with that of a non-D0J0 ops. As a result the single operator was showing stronger excited state contamination. These
are the plots that Herve saw sometime ago that got us excited about a possible improvement of our spectrum and matrix elements calculations at large momentum.<br>
<br>
After fixing this problem my results are in line with Chris’ (and the rumored Robert’s results). The 3 operator GEVP gives no advantage over the single (D0J0) operator.<br>
<br>
As I said on the call, given that the excited state nucleon spectrum has several (N>2) nearly degenerate states close by a 3 operator basis is not expected to solve any problems.
<br>
This is the P=0,0,5 plot<br>
<br>
Cheers,<br>
<br>
