Description
This dataset gives the radial surface brightness profiles for three elliptical galaxies in the nearby Virgo galaxy cluster (Kormendy et al. 2009). They are useful for exercising nonlinear regression in 2-dimensions; the Sersic (1968) profile function is commonly used. The samples are described in Appendix C.11 of Feigelson & Babu (2012) with regression illustrated in Chapter 7.
