An optical polarimetric catalog for the Small Magelanic Cloud (SMC)
is presented. It gives intrinsic and observed polarizations in the
V-band for a total of 7207 stars located in the Northeast and Wing
sections of the SMC and part of the Magellanic Bridge.
This tutorial employs the Aladin VO client to explore neutral
hydrogen shells around the SMC; it demonstrates using image servers,
catalog servers, and advanced overplotting within Aladin.
