I used my NLREG program to fit the function: Y = Base +

Did you just manually fiddle with the parameters?

No, NLREG is a nonlinear regression program. It computed the optimal values for
the parameters.

Here is the NLREG program in case you want to run it yourself:

Is that a programming language? Which one?

It is a program for my NLREG nonlinear regression program. See

Just paste the program and data into NLREG and run it.
