I'm starting a new project on dark matter astrophysics in which I have to extract from some data (I will write some below) the surface brightness, to later construct the mass density profiles of de bulge-disk decomposition. Can anyone recommend me a good, base-solid and specific book/articles on how to achieve this?
Basically, I have the data of:
R(kpc)--Velocity(km/s)--Velocity Dispersion----Intensity of NII----Intensity of H$\alpha$
I've been reading a lot and nobody talks about how to compute it. Actually: Kent S. M., 1986, A J 91,1301 uses a method but it is not based on specific formulas, just took some data from somewhere and does the decomposition.
