Apodizing Phase Plate (APP): Spectroscopy

APP Spectroscopy combined the APP described in the APP Imaging section and long slit grism spectroscopy. Only a few spectroscopic modes are compatible (see User Manual). It is offered with NaCo since P87 in shared risk (high contrast spectroscopy on NACO is subject to the presence of ghosts which can be stronger than the companion the followup is done for).
