Dehnen’s ‘new’ df
(xD,xS,Sro) where
xD - disk surface mass scalelength / Ro
xS - disk velocity dispersion scalelength / Ro
Sro - disk velocity dispersion at Ro (/vo)
Directly given to the ‘surfaceSigmaProfile class, so could be anything that class takes
beta - power-law index of the rotation curve
correct - if True, correct the DF
+DFcorrection kwargs (except for those already specified)
