   Anderson variation of White stimulus as shown in Robinson, Hammon, & de Sa (2007) Fig 1d.
   Grating size: 16x16 deg
   Grating frequency: 0.5 cpd
   Target size: 3.2x1 deg

   :param ppd: Resolution of stimulus in pixels per degree. (default: 32)
   :type ppd: int
   :param pad: If True, include padding to 32x32 deg (default: True)
   :type pad: bool

   :returns: dict with the stimulus (key: "img") and target mask (key: "target_mask")
             and additional keys containing stimulus parameters
