The above author wish to correct some typographical error found in Section 3.

At page no 2660 of the above paper, in Section 3 and at line 5 it should be read as ‘HΛ = −Λc2X2 ρ(X)/c2 where ρ(X)/c 2 is measured in the unit of mass density’. The r.h.s of Eq. (16) should be divided by the term (c2.|c2|), since the trial density is ρ(X)/|c2|. Hence after Eq. (16), Λc2 should be replaced by Λ ∣ c −2∣. Everything else remains unchanged.
