Hectochelle Reduction Information

A Detailed Study of the Velocities produced by Hectochelle

The Hectochelle adds a high dispersion capability to Hectospec's moderate dispersion with a second, very large bench-mounted spectrograph using an echelle grating. Hectochelle uses 240 of Hectospec's 300 fibers and Hectospec's robotic positioner and attains R~32,000 (sigma~4 km s^-1) over single, filter-selected orders.
