Re:NGC 5138
NGC 5128: In Kraft et al. (2000) the nuclear spectrum is modeled assuming a
power-law spectrum with a photon index of 1.9 and N_H_ = 10^23^ cm^-2^. Evans et
al. (2004) compared different nuclear observations of Cen A and confirmed that
the spectrum is well fitted by a heavily absorbed power-law model, consistent
with the previous observation.
