Michalis, it seems to me that your SR Form gives a faulty Zn value. As I haven't figured out how the method is designed I cannot say for sure where the error is, perhaps it is as simple as the Lat = North should be interchanged with Lat = South in the lower right hand corner. Try Ho=12°, Dec=6° and lat=53°. Then you should get LHA=78° and Zn=264°.
