Fitting parameters

Syntax: SCALAR\FIT s1 { s2 ... }
SCALAR\FIT s1[s1min:s1max] { s2[s2min:s2max] ... }

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.
