The Image Shifts due to the FOC Polarizers
by P.E. Hodge

Abstract excerpted from the report:

Observations of NGC 5272 were made with the polarizing filters to
determine the shifts that those filters introduce. The POL0 and 
POL120 images are nearly in the same position, but POL60 is shifted
about three pixels to the left and two pixels down relative to the
other filters.
