... 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. ...

... By dividing the digitized band into several smaller sub­bands, using digital filtering, downconversion and Nyquist subsampling (decimation), one can achieve a significant reduction in the size of the correlator. ... Subbands have different fringe frequency. ... Residual fringe phase across the IF bandwidth may require additional fringe rotation in each subband, depending on the accuracy of the delay tracking. ... Signal is split into N + 2 complex subbands, processed by complex correlators. ...
