Postscript version of plot
Use the data of Verheijen 2001, ApJ, 563, 694 to determine the distance to the UMa cluster of galaxies using the I-band and K-band calibration of the HST Key Project (Sakai et al. 2000, ApJ, 529, 698). Be sure to include a plot of the data with calibration lines overlaid.
Assuming the recession velocity of the Ursa Major cluster is 1088 km/s, what Hubble constant(s) do you find? How does this compare to the value given by Sakai et al.?
* Note that Verheijen gives absolute magnitudes for a presumed distance of 15.5 Mpc. Also note that ascii versions of the tables, convenient for plotting, can be downloaded from the journal website.
** For the K'-band data, use the H-band calibrations assuming H-K = 0.25.
