Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...

Consequently, the calibration for data collected using the hipass 1320 and the hipass 1370 filters only will be mis-calibrated (i.e. by using the opposite polarisation calibration data). ... It is now possible to select any bandpass filter that is not in the 1320 hipass band. ...

This report describes what an HST observer must do to activate a Target of Opportunity proposal and the steps taken by STScI after the request is received. ... In the request the PI identifies which visit (or visits) to activate and supplies all the information needed to implement and schedule the observation on-board HST. ... If the activation request is not approved, you may re-request it at a later time, until the end of the observing cycle when unexecuted ToO observations are withdrawn. ...
