######################################################################
section=dispersive
section_description
These variables control Demeter's treatment of dispersive XAS data
variable=quadratic
type=real
default=0
description
This is the default value for Demeter's initial guess of the
quadratic term for the calibration. 0 is usually an acceptible
value. However if you find that data from a particular detector or
beamline or experiment consistently has a quadratic term of a
certain size, the refinement might be helped along by setting this
accordingly.
variable=bkg_nor2
type=real
default=1000
description
The algorithm for finding the initial guesses for the calibration
parameters is usually helped along by setting a large value for the
bkg_nor2 used in normalizaing the pixel-valued data. The default of
1000 works pretty well for all of Demeter's test cases. This is
currently only used in Athena.
variable=emin
type=real
default=-100
units=eV (relative to e0)
description
This is the lower plotting limit for displaying the calibration
standard along with the calibrated dispersive standard. This is
currently only used in Athena.
variable=emax
type=real
default=400
units=eV (relative to e0)
description
This is the upper plotting limit for displaying the calibration
standard along with the calibrated dispersive standard. This is
currently only used in Athena.
variable=nsmooth
type=positive integer
minint=0
maxint=10
default=4
description
The number of times to apply Ifeffit's three-point smoothing
algorithm the pixel data as part of the refinement.
