RV precision at low resolution

Forums Spectroscopy Measuring radial velocity of planetary nebulae with Alpy? RV precision at low resolution

Robin Leadbeater

I think my limited work with the ALPY suggested a few tens of km precision but high RV precision using low resolution instruments is certainly possible though for example as  David demonstrated at a BAA workshop using a LISA a couple of years back with if I remember, an impressive 5km/s 1 sigma ?
