Supercomputers and fast networks have the potential to remove this delay, so that astronomers can look at the images as the data is recorded. The closer to two objects can be while still allowing the telescope to see them as two distinct objects, the higher the resolution of the telescope. Similar to spatial resolution except that it applies to frequency, spectral resolution is the ability of the telescope to differentiate two light signals which differ in frequency by a small amount. The closer the two signals are in frequency while still allowing the telescope to seperate them as two distinct components, the higher the spectral resolution of the telescope. Right Ascension a coordinate which, along with declination , may be used to locate any position in the sky.
Right ascension is analogous to longitude for locating positions on the Earth.
Observing Run the period of time when observations are made with the telescope for a particular scientific project. Self-Calibration a data processing technique for improving the calibration of data from an interferometer by removing errors cause by disturbances in the Earth's atmosphere. It is called self- calibration because it uses observations of the unknown source, rather than the calibrator source, to improve the image of the unknown source. A highly sensitive telescope can detect dim objects, while a telescope with low sensitivity can detect only bright ones. The smallest spatial features in an image.
