NOTES

IGR J17451-3022 has shown periodicity in its light curve of ∼6.3 h (Jaisawal2015) based on X-ray eclipses and dips which would imply a >70º inclination. The nature of the compact object is still unclear. Zdziarski2016 obtains an inclination of ~73º from the modelling of the duration of the eclipses and the orbital period derived by Bozzo2016 suggesting that the compact object is a neutron star, arguing that if the compact object would be a BH, the inclination would be ≥85º.
