Detailed Description - Ridenlr See /eros/descript/ridenlr.xls for spreadsheet listing of all ridenlr observations. These were MSI observations taken during times when the NLR instrument was commanding pointing. Almost all of these observations were pointed to nadir. A few were a few degrees off nadir. We took MSI images usually spaced equally during the time period, but with time delta selected to make sure we have frame-to-frame overlap. Observation names varied throughout the mission between things like MSI_RideNLR, or MSI_NLRide, etc.
