Mie and other contributions¶

Plus button – add new contribution,
plot button – plot the sum of all contributions,
cross button – delete the last contribution in the list.

Each contribution has the type, a number of parameters and individual plot button.
Possible contributions and thier parameters:
ConstBkg – constant background addition
1.1. shift
LinearBkg – linear background addition (see
mstm_studio.contributions.LinearBackground
)2.1. shift
2.2. slope
LorentzBackground – background contribution mimicing UV-absorbtion of silica glass (see
mstm_studio.contributions.LorentzBackground
) with center at ~ 250 nm.3.1. scale
3.2. peak width \(\Gamma\)
Mie single – extinction of single sphere (see
mstm_studio.contributions.MieSingleSphere
)4.2. scale
4.3. diameter (in nm)
4.4. material label
Note: the enviromnent material will be taken from Matrix field of Spheres panel.
Mie LN – extinction of ensemble of non-interacting spheres with sizes disributed accordint to Log-Normal (LN) law (see
mstm_studio.contributions.MieLognormSpheres
). Actually, the cached version of the class optimized for the fitting is used.5.1. scale
5.2. LN parameter \(\mu\)
5.3. LN parameter \(\sigma\)
The new plot button will show the size distribution:
Note: the window may require widening to show all the parameters and buttons.
Lorentz peak – Lorentzian function (see
mstm_studio.contributions.LorentzPeak
)6.1. scale
6.2. center
6.3. width
Gauss peak – Gaussian function (see
mstm_studio.contributions.GaussPeak
)7.1. scale
7.2. center
7.3. width
