     Parameters
     ----------
 
-    SurfTilt : float or DataFrame
-          surface tilt angles in decimal degrees.
-          SurfTilt must be >=0 and <=180. The tilt angle is defined as
-          degrees from horizontal (e.g. surface facing up = 0, surface facing
-          horizon = 90)
-
-    SurfAz : float or DataFrame
-          Surface azimuth angles in decimal degrees.
-          SurfAz must be >=0 and <=360. The Azimuth convention is defined
-          as degrees east of north (e.g. North = 0, south=180, East = 90,
-          West = 270).
-
     AOI : float or DataFrame
           Angle of incedence of solar rays with respect
           to the module surface, from :py:mod:`pvl_getaoi`.
