ell_gal_profile {astrodatR}

Elliptical galaxy radial profiles

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.

Usage

Format

A table containing 150 rows and 3 columns with header row. It includes 58 entries for NGC 4472, 52 rows for NGC 4406, and 40 rows for NGC 4551.
