Re: Fitting with leasqr and uncertainties

[st.michal88]

Hello Pascal,

  what do I fit to: 
I work on the molecules which can be in one of two spin states, so coled
High-spin state and Low-spin s  state. There are various methods to force
the transition between the two. One of the way is so called LIEEST (light
induced excited spin state traping). It occurs only in low temperatures. So
I cool down the sample containing the molecules and irradiate it with laser.
Molecules undergo LS->HS transition but it evolves slowly in time. So by
indirect measurment I have the evolution of HS proportion vs. time which
behave like exponenta and saturates after some time

  what do I fit with:
Function is more or less: y(t)=param1*exp((t-param2))+param3

Greetings,
Michal
