Look on page 43, at figure 17

the 68 % confidence interval for Omega_k is

[-0.037, -0.008]

this means that the 68% confidence interval for Omega_total is

[1.008, 1.037]

anything over 1 means postive spatial curved finite universe

it is still "consistent" with flat infinite, but the other cant be so easily ruled out

something to keep in mind when thinking about loop quantum cosmology and other types QG cosmology
