• Buffer subtraction necessary?

Subtract buffer for each sample file separately.

Subtract one buffer file for all samples.

No subtraction necessary - CD data is already blanked against buffer.

• Smoothing necessary?

Yes, smooth my data with a Savitzky-Golay filter.

Yes, smooth my data with a Savitzky-Golay filter but also plot my original data.

No, do not smooth my data.
