# 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.
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.
- Both cases, tau_1 positive and negative, are calculated.
Scale determined by minimizing chi².
- Scale determined by minimizing chi²; here
we focus on the tau_1 negative case.
The starting values are based on the dtraj1* results.

## 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.
- Scale determined by fixing 0^++ to Teper's value,
second try
Here is a plot based on the l1_dscan2* and straj1* data:

There is also an Encapsulated Postscript
version.
- Scale determined by minimizing chi².
Here is a plot based on the l1_bscan1* and btraj2* data:

There is also an Encapsulated Postscript
version.
