 def read_fits_polygons(filename):
     """Read a "polygon" format FITS file.
 
-    The main point of this is to extract the xcaps and cmcaps columns
-    and replace them with caps.x and caps.cm, though this is really very silly
-    & is only here so it's similar to IDL.
+    Unlike the IDL version of this routine, the ``XCAPS`` and ``CMPCAPS`` columns
+    are *not* replaced with ``poly['CAPS']['X']`` and ``poly['CAPS']['CM']``.
