Fitting parameters
Syntax: |
SCALAR\FIT s1 { s2 ... }
|
The SCALAR\FIT
command defines sI
to be a scalar variable and
allows sI
to vary for a FIT
command or a
MINUIT
command. If
sI
already is a scalar, the value of sI
will be
unchanged. If sI
is an existing variable, but not a scalar, it will be destroyed first. If
sI
does not exist, it will be created and initialized to 1
.
Use the SCALAR
command with no
qualifier to fix a scalar, that is, to not allow it to vary in a fitting procedure.
The SCALAR
command allows for limits to be placed
on a fitting parameter. Use the a[amin:amax]
syntax to create fit parameter a
with lower limit
amin
and upper limit
amax
. To set an upper limit only, use
a[:amax]
, and to set a lower limit only, use
a[amin:]
. These limits are only used by the
MINUIT
command and are ignored by the
FIT
command.
