  In our previous paper (Masiero et al. 2007) we presented the design and
initial calibrations of the Dual-Beam Imaging Polarimeter (DBIP), a new optical
instrument for the University of Hawaii's 2.2 m telescope on the summit of
Mauna Kea, Hawaii. In this followup work we discuss our full-Stokes mode
commissioning including crosstalk determination and our typical observing
methodology.
