.. py:function:: stimupy.papers.RHS2007.WE_thin_wide(ppd=PPD, pad=True)


   White stimulus as shown in Robinson, Hammon, & de Sa (2007) Fig 1b.
   Grating size: 12x16 deg
   Grating frequency: 0.5 cpd
   Target size: 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
   :rtype: dict of str
