For comparison with a detailed H I survey, we calculated models for th
e H I intensity distribution, T(B)(l, b, v), for a 18-degrees x 12-deg
rees region in the disk of the Galaxy toward l = 205-degrees. In one c
lass of models, neutral hydrogen is in the form of clouds, while in th
e other class of models it is a continuous medium with holes whose siz
es are typical of supernova remnants and superbubbles. The cloud model
s are a poor representation of the data in that the amplitude fluctuat
ions are dissimilar and the continuity of the H I observations is not
reproduced. A continuous H I medium with holes provides a much better
match to the data, and the best-fit models suggest that the filling fa
ctor for the H I is 20%-50%.
