We assume a plane parallel atmosphere of scale height 0.11kpc, with a mean extinction of 0.7 magnitudes per kiloparsec. Thus a star at high Galactic latitude, at distance "D" from the Sun, is assumed to have a line of sight extinction [A.sub.v]=0.7 mags/kpc up to distance "x" (the limit of the Galactic disk) and [A.sub.v]=0.7 henceforth (Fig.
Pennypacker says that on the basis of observations made so far, they have calculated a "preliminary' value of the Hubble constant to be 100 kilometers per second per kiloparsec. However, they do not claim great accuracy for this, saying only that they are within 45 percent of the true value.
