Optical Filters . The polarizer quads were also designed to map onto a four-faceted WFC configuration and, consequently, also require a partial filter rotation of -33 degrees to move the filter quadrant 1 (nominal polarization angle 135 degrees ) into WFCs 2 and 3, with some vignetting of both camera fields. Several additional partial rotations have been added to allow observations with different polarization angles on the same CCD. ...

... Animation . Arrow . ... I created the first animation by running Script-Fu / Animators / Fire on the head of an arrow. ... I merged the animation with the background image, and specified a final X offset of -128 (the background is 128 pixels wide). This results in an animation with a nice moving background. Note that you can also use a background that is wider than the image, as long as you specify the width of the background for the final X offset if you want the final animation to loop. ...
