DABAX tools
DABAX is the database that contains the necessary tables for XOP.
It contains some files and related applications that could be useful
for XAFS users. More information on DABAX can be found from the XOP
website (
http://www.esrf.fr/computing/scientific/xop)
DABAX applications and files interesting for XAFS users
- Tables of atomic scattering factors f1 and f2: the XF1X2
application calculates f1 and f2 (scattering factors) and related
quantities (refraction index, photoelectric absorption) for
elements and compounds.
You can start it from the main XAFS window (Start...->DABAX->
f1 and f2 values)
- McKale phases interpolates the tabulated McKale phases.
You can start it from the main XAFS window (Start...->DABAX->
McKale phases).
This application and the corresponding DABAX
file are installed by default when installinf XAID as XOP extension.
- EXAFS spectra database. The DABAX file
XAFS_DATA_EXAFS_CHI.dat can be installed optionally. It contains
hundreds of EXAFS spectra kindly made available by Farrel Lytle trought
the IXS XAFS database.
See installation notes for
installing it in your XOP copy.
You can start it from the main XAFS window (Start...->DABAX->
EXAFS spectra database).
- XANES spectra database. The DABAX file
XAFS_DATA_XANES.dat can be installed optionally. It contains
hundreds of XANES spectra kindly made available by Farrel Lytle trought
the IXS XAFS database.
See installation notes for
installing it in your XOP copy.
You can start it from the main XAFS window (Start...->DABAX->
XANES spectra database).
Installation of EXAFS and XANES databases
The files of these databases are not installed by default, because
they are quite big (tens of Mb). For installing them, do the following:
- Download (transfer in ASCII mode) the files XAFS_DATA_EXAFS_CHI.dat
and or XAFS_DATA_XANES.dat from the
ftp://ftp.esrf.fr/pub/expg/xop/Beta1/dabax/ directory to the
data/dabax directory in your XOP installation.
- Download (transfer in BINARY mode) the files XAFS_DATA_EXAFS_CHI.HIld
and or XAFS_DATA_XANES.HIld from:
to the data/dabax directory in your XOP installation.
- restart XOP and XAID.
