I enjoyed seeing your light curve, Kevin.
You can submit the data as “Clear” filter (abbreviated to C).
For some purposes (like time series photometry of cataclysmic variables), C is perfectly acceptable (when you use a filter, you lose some of the light, so your signal to noise deteriorates). However, for many applications a filter is much preferred as it’s easier to compare data from different observers.
