WebAstrometry is one of the most limiting factors in revealing complex multi-wavelength structures of sources. The precise determination of the offsets between the radio and optical emission relies on accurate astrometry. For example, the HST absolute astrometry has a typical uncertainty of 0.2”–1”, which is greater than the angular resolution. WebAbstract The field of optical and infrared (IR) interferometry has seen rapid technical and scientific progress over the past few years. A number of instruments capable of precise visibility measurements have been built, and closure-phase imaging with multitelescope …
