# Do we know at which angle the Event Horizon Telescope will look at the accretion disk of Sagittarius A*?

Do we know at which angle the Event Horizon Telescope will look at the accretion disk of Sagittarius A*? Additionally, would it matter if we are exactly in the plane with the accretion disk, i.e. could we still observe the event horizon?

• Are you asking what the angular resolution of the EHT is or the declination and right ascension of Sagittarius A*? – Beta Decay Jul 18 '18 at 12:04
• @BetaDecay I am not asking for the angular resolution. I am not so familiar with the terminology, but what I would like to know is how the accretion disk looks from earth (flat line or disk) and how this influences the expected images from EHT. – user3095304 Jul 18 '18 at 13:14

After some research, I think this answers my question: The orientation of the disk seems not to be known with certainty, however, Meyer et al. (2007) gives estimates with $3\sigma$ confidence that "the position angle is ∼60◦−108◦ (east of north) in combination with a large inclination angle", meaning that the disk is seen more or less edge on.
