KPF Reduced Products Science Ready (Lev2)
KPF raw data is processed via the KPF DRP. When available, a Science Ready ("Lev2") link is shown in the search results "Previews" column for individual KOAIDs. When downloading KPF 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:
