Contributed Datasets
Certain projects, scientists, or time-granting institutions have publicly released datasets relating to a specific target or set of targets. These “contributed datasets” are listed below. Some contributed datasets contain only the raw data; others include extracted spectra or images, or higher level products. Please see each Dataset page for details.
To submit contributed data to KOA, please contact the KOA Help Desk and refer to the Contributed Data Set Policy.
