T1 - Extraction of low dispersion spectra for INES Y1 - 1998 SN - 03764265 UR - http://hdl.handle.net/11268/6246 AB - In this paper we outline the modifications introduced to the optimal extraction algorithms for IUE Low-Dispersion data under INES. A major modification has been the creation of new noise models for the three cameras, in order to improve the handling of very high and very low FN values. Other changes affect the background estimate, the extraction profile determination and the treatment of nagged pixels. Altogether, the changes do not affect significantly to the vast majority of IUE Low-Dispersion data, but definitely improve the quality for those cases where SWET was known to produce unsatisfactory results.
