The disk-like component is elongated along PA ~ 46° and oriented perpendicular to the ionisation cone and outflow.

The extended component is responsible for 80% of the mid-infrared emission. It is elongated along PA ~ °, which is roughly perpendicular to the disk component and thus in polar direction.

High Time Resolution Astrophysics (HTRA) is an important new window to the universe and a vital tool in understanding a range of phenomena from diverse objects and radiative processes. The optical emission line variations were observed to be correlated with the optical continuum [12], and the emission line flares were found to exhibit a double-peaked line High-Speed Optical Observations of X-ray Binaries 43 profile, suggestive of emission distributed across the accretion disk rather than arising in localized regions.
