@matthewross07 Are you thinking mean and st.dev for all the bands or just for Swir 1 to use for filtering?

I think this should be for all bands, unless it adds hours of run time. Not necessarily going to be used, but good to start with max data and we can drop parameters later...?

I second doing it for all bands. I just had to go back through and add that into my code so I could calculate a coefficient of variation for use later in the data screening process.

People use a CV threshold to drop noisy points. For example, if you are using the red or NIR band to calculate a sediment index, you can use the CV to drop any noisy points. Helps to get cleaner data.

We now pull median and sd for all bands.
