Purpose
The Program Identification GUI (PIG) allows observers on split nights
to easily indicate which observing program is currently being
executed. This information permits the Keck
Observatory Archive (KOA) to tag the images with the
appropriate observing program and observer list, and ensures that
the data files are assigned the correct proprietary period.

By clicking the button on the appropriate observing program, the
observer changes both the observer list (stored in the
OBSERVER keyword) and the data directory (generally
stored in the OUTDIR keyword).
The PIG also allows you to select an approved target of opportunity (ToO) program. These programs are normally hidden under the "Show ToO Programs" button at the bottom left. Click on it, and the PIG is expanded to display a list of approved ToO programs. Click on the program's ID to select. Make sure to click back to your scheduled progam on top after the ToO interrupt is over! For details, see the full ToO policies and procedures.
