TRES Showcase
TRES spectra cover the wavelength range 3860A to 9100A in 51 orders,
with sharp, stable lines and good throughput from tip to tail. Order
width goes from 75A in the blue, to 170A in the red, with 100A coverage
at aperture 23. R = ~36,000 for the standard observing mode with the
2.3" M fiber, binned (0.0663A/binned pixel, 4.1 km/s per binned pixel
at 5200A?). There is some overlap in the blue and middle orders, and
small gaps in coverage between the red orders. Extracted aperture #1
corresponds to order #88 (blue), aperture #51 corresponds to order #38
(red).
