Univariate probability density distributions for the longitude component of error for Argos locations compared to matched Fastloc GPS locations by location class (LC) calculated for three large whale species (sperm, blue, and fin). Data were collected from sperm whales tracked in the Gulf of Mexico during summer 2011 and 2013, and from blue and fin whales tracked off southern California during late summer 2014 and 2015
