Table 3:
Parameters of best-fitting King model (core radius,
,
tidal radius,
),
Sersic model (Sersic radius,
,
shape parameter, m), exponential model (scale radius,
)
and Plummer model (scale radius, b)
for all stellar populations, intermediate age and old stellar components in Fornax dSph. For each model
we also compute the half-number radius,
;
for the Plummer model this coincides with b. The
errors in the parameters are formal errors from the fitting procedure.
