Not an intentional alignment .
What distinguishes a clearly intentional alignment is that there is a obvious indication of the orientation e.g. the passage at Newgrange ,all man made and you have no choice of where to look ,similarly Maes Howe , Loughcrew ,Stonehenge from the centre of the monument and on the alignment of the Avenue , the Avenue itself is enough being man made and giving little option as to the orientation .recumbent stone circles from the centre of the monument across the centre of the recumbent or between the flankers . etc . When one of the points of a putative two point alignment is chosen simply because it fits an agenda and has no prehistoric significance then it is very difficult to argue for intentionality and wouldn't likely be considered a contender by archaeoastronomers . Another problem with the Carrickaruppara might be the distance i.e. 2.5 Km to a 2m plus stone ,can the stone be that clear at that distance ?
