Appendix A: The velocity dispersion profile of NGC 4636
NGC 4636 velocity dispersion profile from FORS 2 data.
Appendix B: The stellar mass profile of NGC 4636
Here we give the piecewise approximation of the stellar mass profile of NGC 4636 (see Sect. 10.2) used in our modelling. In the following expressions, x is in units of parsec, D is the distance of NGC 4636 in Mpc (assumed to be D = 17.5 in our modelling), and Υ ⋆ ,R ( = 5.8) is the R-band stellar mass-to-light ratio.
For 0 < x ≤ 3.0·D: (B.1)for 3.0·D < x ≤ 29.184·D: (B.2)where a0 = 1.322 × 107, a1 = −1.118 × 107, a2 = 3.158 × 106, a3 = −9.127 × 104, and a4 = 1.164 × 103.
For 29.184·D < x ≤ 104.49·D: (B.3)where b1 = 9.616 × 106, b2 = 1.034 × 106, b3 = −9.133 × 103, and b4 = 25.78.
For 104.49·D < x ≤ 2597.9·D: (B.4)where c0 = 6.101 × 108, c1 = 4.31 × 107, c2 − 1.507 × 104, and c3 = 1.996
For x > 2597.9·D(B.5)where d0 = 1.194 × 103, d1 = 4.221 × 1010, d2 = −0.0668, and d3 = 0.003774.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.
An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
