New Spectral Image Processing System (NEWSIPS)

The New Spectral Image Processing System, known as NEWSIPS, is the second (and final) generation standard production processing system used for IUE data. The processing system incorporated a number of improvements and enhancements in the reduction algorithms, calibrations, documentation, and output formats of the IUE data. The NEWSIPS-processed data, known as the IUE Final Archive, generally provide improved signal-to-noise, improved absolute calibration, and more homogeneous results for IUE data than the IUESIPS-processed data.

Among the major enhancements are the following:

The history behind the development of the NEWSIPS system and creation of the Final Archive, a discussion of the reduction techniques and new calibrations, and an examination of the resulting processed data are discussed in a paper by Nichols and Linsky 1996.
