Flow
You can determine, if you want to fit to the
diffusion time or to the velocity directly by un-
ticking or ticking the
Velocity
check box (Fig. 70).
In the latter case you have to provide the radial
dimension of the confocal volume in the
ω
r
selection box. Type in the number or use the arrow
keys.
The description box gives you information on the
flow terms. Note, that the system automatically
toggles between the pure flow and flow in
combination with translational diffusion in cases
where the
Translation
term is deactivated or
activated, respectively.
Stretched exponential
You can select between bunching and anti-
bunching terms by pressing the
Bunching
or
Antibunching
buttons, respectively (Fig. 71).
You can select between 1 (mono exponential) or 2
(double exponential) stretched exponential terms
by pressing the
Components 1
or
2
buttons. The
active option will be displayed in blue
You can select between normalized and non-
normalized terms by selecting / deselecting the
Normalized
check box.
You can select between dependent and
independent stretched exponentials by choosing
from the
Components
drop down menu. This
becomes only available, if two components are
active.
Note, the frequencies and stretch factors are
no fit parameters and must be defined in the
Frequencies k
1
and
k
2
as well as the
Stretch
factors
κ
1
and
κ
2
display boxes. Either enter
a value or press the
1
button for the default
setting.
The description box will give information on the
stretched exponential terms.
For two components, only the formula for
dependent processes is presently available.
