The following narrow band filters in IRDIS produce ghosts in their images because of internal reflections:
N_PaB
N_H2
N_CntK1
N_CntK2
N_BrG
N_CO
N_FeII
N_HeI
N_CntH
N_CntJ
Saturated and unsaturated images of a point source are shown below to help identify the locations of the ghosts . Also included below are links to FITS files for the images.
