./wip/py-corrfitter, Utilities for fitting correlators in lattice QCD

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 3.7, Package name: py27-corrfitter-3.7, Maintainer: jihbed.research

This module contains tools that facilitate least-squares fits, as functions
of time ``t``, of simulation (or other statistical) data for 2-point and
3-point correlators of the form::
Gab(t) = <b(t) a(0)>
Gavb(t,T) = <b(T) V(t) a(0)>
Each correlator is modeled using |Corr2| for 2-point correlators, or
|Corr3| for 3-point correlators in terms of amplitudes for each source
``a``, sink ``b``, and vertex ``V``, and the energies associated with each
intermediate state. The amplitudes and energies are adjusted in the
least-squares fit to reproduce the data; they are specified in a shared prior
(typically a dictionary).

An object of type |CorrFitter| describes a collection of correlators and is
used to fit multiple models to data simultaneously. Any number of
correlators may be described and fit by a single |CorrFitter| object.
|CorrFitter| objects can also be used to to extract the appropriate fit
data from |Dataset| objects.

This module has been used extensively for analyzing results from lattice
QCD simulations

Log message:
Mark packages as not ready for python-3.x where applicable;
either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE=  33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE=  33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.

Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.

Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.

Whitespace cleanups and other nits corrected, where necessary.
