This Very Important Project (VIP) list is intended as part of the LAT legacy program. These are AGN of special interest. The concept is to have someone watch each one closely, encourage multi wavelength studies, and possibly even organize full multi wavelength campaigns. These are ones for which we will make a particular effort to cooperate with anyone doing studies.
