Information for 2+1 Transverse lattice.

To produce these results, we wrote lots of C-code and a Makefile. This code is linked to standard packages BLAS and LAPACK along with some other standard routines. I have gotten the code to run on a CRAY T3E, IBM SP2, a Fujitsu VPP300 (in fact, we found that the code doesn't vectorize very well), a gnu C compiler under Linux, a Convex parallel computer, and on a Hewlett Packard workstation with HP-UX. There is a parallelized version which uses MPI; it works efficiently on up to about 20 processors.

Older data from 1999

All plots are in encapsulated postscript format.

Scaling Trajectory

The following uses the new large basis (August 2000). There seems to be a good fit for tau_1 either positive or negative.

Both cases, tau_1 positive and negative, are calculated. Scale determined by fixing 0^++ to Teper's value.
- dtraj10.out, small masses.
- dtraj11.out, medium masses.
- dtraj12.out, large masses.
Both cases, tau_1 positive and negative, are calculated. Scale determined by minimizing chi².
- btraj10.out, small masses.
- btraj11.out, medium masses.
- btraj12.out, large masses.
Scale determined by minimizing chi²; here we focus on the tau_1 negative case. The starting values are based on the dtraj1* results.
- btraj20.out, small masses.
- btraj21.out, medium masses.

Scans of parameter space: m and lambda_1

The following uses the new large basis (August 2000). I have chosen tau_1 to be negative.

Scale determined by fixing 0^++ to Teper's value.
- l1_dscan10.out, small masses.
- l1_dscan11.out, medium masses.
- l1_dscan12.out, large masses.
Scale determined by fixing 0^++ to Teper's value, second try
- l1_dscan20.out, small masses.
- l1_dscan21.out, medium masses.
- l1_dscan22.out, large masses.
- l1_dscan23.out, large masses.
Here is a plot based on the l1_dscan2* and straj1* data:

There is also an Encapsulated Postscript version.
Scale determined by minimizing chi².
- l1_bscan10.out, small masses.
- l1_bscan11.out, medium masses.
- l1_bscan12.out, large masses.
- l1_bscan13.out, large masses.
Here is a plot based on the l1_bscan1* and btraj2* data:
