Corrigenda to Inhomogeneous universes in observational coordinates (vol 13, pg 253, 1996)

Four corrections should be made to this paper:

1. The right-hand side of equation (20) should be -½mN*AB/C³.

2. The equation before (23) should read v2 + 2uv = 1 -mN*/C.

3. The factor M in equations (42) and (43) should be replaced by N'.

4. Point (iii) at the end of section 3 implicitly assumes Ȧ (w₀, y) = Ḃ(w₀,y). It should
be replaced by:
(iii) A past null-cone integral for F.y/ may be obtained from equations (24) and (27):

F(y) = 1/2I ∫[(Cv² + C)'/Cv] Idy

where

I(y) = Cv exp (1/2 m ∫ N'/Cv dy)
