     37 Set the rotation of the raster. This method actually derive values for pixelsizex, pixelsizey, skewx and skewy based on the provided rotation angle.
     38
     39 '''Open Question:'''
     40  PR: The angle should be provided in radian or in degree?
     41
     42'''ST_Rotation(raster) -> float64'''
     43 Return the georeference's rotation angle in (degree or radiant?) derived from the pixel size and the skew.
     44
     45  PR: I think getting the rotation get no sence since the result of pixelsizes and skew is not necessarily a rotation.
