[18.18] A Wavelet-Based Method to Remove Fringes from Images

P.M. Rojo, J. Harrington (Cornell University)

We have developed a new method that uses wavelet analysis to remove interference fringe patterns from images. This method is particularly useful for spectroscopic flat fields in the common case where fringes vary between the calibration and object data. We analyze the efficacy of this method by creating fake flats with fictitious fringes and removing them. We also present examples using real flat field frames. The routine is written in the Interactive Data Language (IDL) and it is available from the authors.
