NIRES Reduced Products: Science Ready (Lev2)
NIRES raw data is processed via the NIRES DRP. When available, a Science Ready ("Lev2") link is shown in the search results "Previews" column for individual KOAIDs. When downloading NIRES data, choose "Include extracted/calibrated data" to receive a script (curl and wget options) to download all the individual products.
