Their removal is a rather delicate step, because in high-contrast images (such as well-exposed echelle spectra) there is always a danger of damaging the scientific contents of the frame. Particle hits can be removed from scientific exposures by splitting the exposure and comparing spectra of the same target obtained under the same instrumental configuration. ...
