Cosmetic for UVES Blue Upgrade

flat field

For the flat field we use three wavelengths, 350nm, 600nm and 900nm. For each wavelength we make two images, high level (45000 ADU) and low level (1000 ADU).

350nm (UV), Bandwidth 5nm, High gain mode, High level

475nm, Bandwidth 5nm, High gain mode, High level

600nm, Bandwidth 5nm, High gain mode, High level

750nm, Bandwidth 5nm, High gain mode, High level

900nm, Bandwidth 5nm, High gain mode, High level

350nm (UV), bandwidth 5nm, High gain mode, Low level

475nm, bandwidth 5nm, High gain mode, Low level

600nm, bandwidth 5nm, High gain mode, Low level

750nm, bandwidth 5nm, High gain mode, Low level

900nm, bandwidth 5nm, High gain mode, Low level

350nm (UV), bandwidth 5nm, Low gain mode, High level

475nm (UV), bandwidth 5nm, Low gain mode, High level

600nm (UV), bandwidth 5nm, Low gain mode, High level

750nm (UV), bandwidth 5nm, Low gain mode, High level

900nm (UV), bandwidth 5nm, Low gain mode, High level

350nm (UV), bandwidth 5nm, Low gain mode, Low level

475nm (UV), bandwidth 5nm, Low gain mode, Low level

600nm (UV), bandwidth 5nm, Low gain mode, Low level

750nm (UV), bandwidth 5nm, Low gain mode, Low level

900nm (UV), bandwidth 5nm, Low gain mode, Low level
