What is the correct way to normalized spectral data?
)
August 21st, 2009
I have a series of spectra. I have summed the data points within certain bins to create a histogram which represents the peaks I am interested in. I wish to compare these bins meaningfully by normalizing them.
For each bin, I have tried dividing by two factors:
1) Divide by the sum total of all bins (for one spectrum)
2) Divide by the mean of all bins (for one spectrum)
When graphed, the resulting normalized bins using both methods appear identical. I’m not sure if it’s the correct way, however.
What is the scientifically accepted way to normalize data?
