Outline of the BTF paper by Erwin de Blok (25-2-2002) ----------------------------------------------------- * Description of sample * Data and corrections * Descriptions of method to measure line widths * Description of method to measure inclinations * Corrections to linewidths and magnitudes (inclination, random motion, instrumental resolution, extinction) * Corrections to recession velocities (to Local Group frame, also POTENT etc for nearby galaxies) * Describe B-band data - note heterogeneous nature * Use CCD data or raw LEDA data to estimate uncertainty in magnitudes * 2MASS data * Describe 2MASS data * Compare uncertainties with optical data * Classical TF * Plot classical TF. * Determine slope and scatter using B and 2MASS. * Baryonic TF * Describe Baryonic TF principle * Apply correction * Determine slope and scatter. * Compare with classical TF. * Any sign of break at 90 km/s * Conclusions * Has BTF really improved TF? * Did 2MASS data help? * Does it tell us anything about Dark Matter?
