$EREF$plot2 module <fit>

This module allows fitting of families of peaks.
$<DL>$
$<DT>${no fit : Ax+B : log(Aexp(-Bx)) : Aexp(-Bx) : Aexp(-BX)+C} <fit_method>$<DD>$
The method used for fitting.
$<P>$no fit: no fit done
$<P>$Ax + B: straight line fit
$<P>$log(A exp(-Bx)): straight line fit of log of data
$<P>$A exp(-Bx): nonlinear exponential fit of data
$<P>$A exp(-Bx) + C: nonlinear exponential fit of data with baseline offset
$<P>$The fit is automatically updated.
(The nonlinear fitting might not work perfectly.)

$<DT>${peak sets} <select>$<DD>$
The peak set (family) to fit can be selected with the mouse.
The fit is automatically updated.

$<DT>${next} <next>$<DD>$
Select the next peak set in the list.
The fit is automatically updated.

$<DT>${previous} <previous>$<DD>$
Select the previous peak set in the list.
The fit is automatically updated.

$<DT>${apply} <apply>$<DD>$
Update the fit drawing (should not be necessary to hit this
since the fit is always automatically updated).

$<DT>${dismiss}$<DD>$
Close the module (the parameters are remembered).

$<DT>${help}$<DD>$
Display this message.
