Lund_2023_GaiaNIR The Hidden Regions Astrometry in the Near Infrared David Hobbs Lund Observatory Sweden What to do first? Photometric filter bands need to be studied - dispersion or filter photometry or both? An RV spectrograph - which wavebands in NIR - the need for high resolution spectra? Periods of slow scanning law need to be studied - for spectra only! Crowding in GC needs to be studied - l
