... This implies that the shadows of the grid wires on the detector are not properly removed by the COS pipeline. ... In some instances, the shadows of the grid wires produce an artificial broadening of the absorption lines in the spectra. ...
... corrections must b e accurate to correct grid shadows with a flat field, but excluding the flagged regions is effective regardless of the shadow shap e. The regions can also b e made slightly wider than the actual shadows to accommodate misregistration ...
