Left: foreshortening factor for the size of any structure calculated for the DSO orbit with inclination i = 113°. Right: relative tidal stretching and compression as function of time (in years with respect to the peribothron passage) in the orbital plane (solid lines) and with respect to the inclined orbit to the DSO (dashed lines).
