Surface brightness limits

Table 7 shows the magnitude levels corresponding to their 1, 2 and 3 from the standard deviation above the residual background noise. These are the surface brightness values we use as maximum limits of how deep we can reach into the galaxy. The last column contains the $\mu_\textrm{\scriptsize crit}$ values, which is the critical surface brigthnbrightnesswhere we really trust the profile, i.e. where beyond the $\pm1\sigma$ profiles deviate by more than 0.2 mag (see figure 2 in Pohlen & Trujillo 2006) for the profile obtained using our mean residual background values of Table 3. See Appendix A for examples.
