K
1

are fit parameters; k
1
is a fixed parameter and must be user defined;
κ
1
is either a fit parameter
or can be fixed.
Note, fixing k
1
and
κ
1
to "1" result s in a simple anti-bunching term.
B.4 Double stretched exponential – anti-bunching
This is a double exponential function, where the exponentials are subtracted.
