... Up: Software Systems and Tools . ... This case study examines the use of the latest software techniques for merging independent Java applets and applications. STScI's new Java interface to the archive, StarView II, will make use of the ST-ECF stand-alone FITS image viewer JIPA. We discuss how state-of-the-art software techniques like Remote Method Invocation (RMI), multithreading, and the Reflection API influence the design of a common interface between StarView II and JIPA. ...

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. ...

instr> Quality Control: . Image flats . ... noise parameters | ... linearity, gain . ... While the ordinary, daily fibre flats mainly measure fibre characteristics, the image flats are exposures of the CCD by the flat field lamp without the fibre system. ... Two kinds of small-scale fluctuations exist in any raw frame: photon noise, and fixed-pattern (gain) noise (the third source, read noise, is negligible here). ... The penalty to pay is added photon noise, inherent in the image flats. ...
