DEIMOS Reduced Products Quicklook (Lev1) and Science Ready (Lev2)
DEIMOS raw data is processed via the DEIMOS DRP. When available, a Quicklook ("Lev1") and Science Ready ("Lev2") link is shown in the search results "Previews" column for individual KOAIDs. When downloading DEIMOS data, choose "Include extracted/calibrated data" to receive a script (curl and wget options) to download all the individual products. The products are of the form:
