30 December 2025 -
New (statically) compiled version using a Kubuntu 24.04 LTS Linux and a
gcc compiler (gfortran), version 13.3. Linux Kernel 6.8.0-86.

Some programs were slightly debugged and updated. Native fortran codes of
the Cern libraries (not supported anymore) were also compiled using the same
Linux system.

The current compiled and supported programs are

contour
crymol
deconv
edxrd
fitedg
fitheo
gdrerr
gnpeak
gnxas
grfit
grrec
grxas
jesf
peakfit
phagen
phaplo
phaplo_c
readder
smooth
xanes
xasam


Other utility files are
gnxas.alias (defining the standard path for gnxas programs)
fitheo.sh (to run fitheo and see the fit evolution on-screen)
sh_multi* (gnuplot scripts for 1-3 edge refinements)

Some information about the current distribution can be found in
the GnXASupgrade.pdf document.

More infos about the current distributions can be found below.

This is the current updated version of the GNXAS extended suite of programs for
advanced x-ray absorption data-analysis.

This version incorporates several advances described in the update of the
documentation (pdf file GnXASuprgade2023.pdf) including the upgraded programs
phagen,* gnxas, fitheo and more**.

Details about usage and features of the programs can be found in the GNXAS
manual available upon request (http://gnxas.unicam.it, ISBN 978-83-908112-8-4).

Programs upgraded in 2024 have been tested for one year and some bugs have
been fixed.
Dimensioning of some vectors have been increased allowing treating data of
larger size.
Some minor utility programs have been eliminated in this release as they are
not used anymore.
Other utility programs like gdrerr, smooth, peakfit and edxrd have been included.

Other important additional features are included in the present release:

* The phagen program calculates the scattering matrix including relativistic
effects.  The program was mainly coded by C. R. Natoli and tested by N. Hara,
A. Di Cicco and G. Tchuodinov.
Filename extensions for the most used scalar relativistic phase shifts are .sr
(scattering matrix), .s0_sr (atomic cross-section). They can directly substitute
files .tl and .s0 produced by 'phagen'.
Details can be found elsewhere.

** The rapid EXAFS extraction JESF routine has been revised for handling
datafiles produced at modern beamlines. The usage is self-explanatory, output
files for gnuplot and TopDrawer include relevant curves related to the EXAFS
extraction (spline, normalization, derivative, EXAFS curves, Fourier Transform).
