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.
