These are better defined on the following website than in Carroll’s book:

a) Eddington Finkelstein

v = t + r + 2m loge sub e (r / (2m) -1)

ds squared = (1 - 2m / r) dv squared - 2 dv dr - r squared d omega squared

b) Kruskal

u = ( r / (2m) - 1) power half exp (r / (4m)) cosh (t / (4m))

v = ( r /(2m)) - 1) power half exp (r / (4m)) sinh (t / (4m))

ds squared = - (32 m cubed / r) exp ( -2 / (2m)) (du squared - dv squared) - r squared d omega squared

We can again run these through our code.
