[45.07] Method for Removing Blemishes from IUE Background

R. P. Fahey and J. M. Bogert (GSFC)

This poster presents a method for removing extended cosmic ray blemishes from the background of IUE high dispersion images during the automated portion of the production of the IUE final archive using NEWSIPS. We take advantage of the fact that the correlation of one row in the image with the next one can pick out statistically significant similarities in adjacent parts of the interorder background. This method appears to be faster and more conclusive than using a 2-D FFT to find, for example, a recurring pattern.
