Actions
- Create sips. Aras Bozkurt Emanuela Orru Hanno Holties provide Kelley an example of a sip.
- Hanno Holties Emanuela Orru check if Roy could help with the specification of the sip.
- Kelley create a table of all individual data products trying to divide the science data products with respect to the ancillary data products.
