Assignment for next Friday
Recreate Hubble’s 1929 plot using the same
galaxies he used, but use modern values.
You will probably need to use NED (NASA Extragalactic
Database) and/or NASA’s ADS abstract service to find
these values.
Make a nice plot using the plotting package of your
choice (e.g., IDL, sm, igi, by hand).
Get the slope (method of your choice, some are
better than others) which is the Hubble constant.
Compare your value to Hubble’s and to the
modern value.  What’s going on?
You might want to learn to use LaTeX, too.
