Final Fit
Now, plot the data to see how well your new model appears to fit the
data. Remember to use the easyplot command:
easyplot 0.5 10.0
Screen capture of the POW plot window showing the results of the
fitting the revised model with a notch for the absorption line.
Answer these questions about your current model and plot:

Note the chisquared for this fit.

How has the chisquared changed since your first model? Does
this change indicate that the fit is better or worse?

How has the chisquared changed since you added the notch? Does
this change indicate that the fit is better or worse?

Looking at your plot, how well does the model match the data?
How has the fit of the model to the data changed since your
first plot?

Zooming in on 6.0 to 8.0 on the xaxis (easyplot 6.0 8.0), does the model fit the
absorption line better than before?

Do you think that you have found the best model for these data?
Why or why not?

If not, then describe what features of the data the model seems
to be missing.
