######################################################################
section=edgestep
section_description
These parameters determine how background removal and normalization
is done by Demeter.
variable=fullreport
type=boolean
onvalue=1
offvalue=0
default=false
description
Tell a GUI to issue a full report on the edge step calculation.
variable=samples
type=positive integer
default=20
maxint=10000
description
The number of samples to use in estimating the edge step
uncertainty.
variable=margin
type=real
default=2.5
description
The size of the margin for weeding out outliers. This is an attempt
to remove obviously poor normalizations from the sampling of
normalization parameter values. On the first pass, the standard
deviation of the edge step values is computed. All values which lie
this many standard deviations away from the initial edge step value
will be removed from the sampling and the standard deviation will be
recomputed.
variable=pre1
type=real
default=20
units=eV
description
The size of the bubble around the initial bkg_pre1 value from which
an evenly distributed random value will be chosen for bkg_pre1 for
each sample.
variable=pre2
type=real
default=10
units=eV
description
The size of the bubble around the initial bkg_pre2 value from which
an evenly distributed random value will be chosen for bkg_pre2 for
each sample.
variable=nor1
type=real
default=15
units=eV
description
The size of the bubble around the initial bkg_nor1 value from which
an evenly distributed random value will be chosen for bkg_nor1 for
each sample.
variable=nor2
type=real
default=30
units=eV
description
The size of the bubble around the initial bkg_nor2 value from which
an evenly distributed random value will be chosen for bkg_nor2 for
each sample.
