Notes. T = Torus, MYT = MYTorus, MYT D = MYTorus decoupled.

(a)

Data for NGC 2960 are just a NuSTAR 3σ detection, so we used the Cash statistic (Cash 1979) for fitting purposes. We report the reduced χ2 just for its straightforward interpretation.

(b)

Normalization at 1 keV of the direct power law in units of photons keV-1 cm-2 s-1.

(c)

Following Murphy & Yaqoob (2009), AS90, AL90, AS00, AL00 are just multiplicative factors of the respective components, and such, lack physical units. To obtain normalizations at 1 keV in units of photons keV-1 cm-2 s-1, the reader should multiply these factors for the primary normalization, i.e. AZ90.

(d)

Luminosities are intrinsic, i.e. corrected for absorption.

(e)

The Eddington ratio is calculated as κbol×/LEdd, where κbol = 20 ± 5 is the bolometric correction, constant in our range of 2−10 keV luminosities.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
