Fitting
For numerical way try doubling the x range
look at running the fit for more iterations to get correct value
wings have some other complicated structure
restrict
and
to be positive and put bounds on parameters
run the fit to get good guesses to speed up the fitting process
Look at the published vega lines and determine whether parameters are similar
look at eloide [http://atlas.obs-hp.fr/elodie/] spectra,
look at data file
convolute with our instrumental response and compare to our fit
Plot a vertical dotted line for the real value of
Look at how
scales with the central value of the line
look at finding physical parameters from the
and
Errors
think about what is causing the fluctuation within the lamp
Look at using a larger gain, as could be an underestimate
could be the noise of the electronics,
Look at the errors when the CCD is cooled right down
