We measured organic volatiles (CH4, CH3OH, C2H6, H2CO), CO, and water in comet 8P/Tuttle, a comet from the Oort cloud reservoir now in a short-period Halley-type orbit. We compare…
A new Generation of Spectrometer Calibration Techniques based on Optical Frequency Combs
Piet O. Schmidt, Stefan Kimeswenger, Hans Ulrich Kaeufl
Typical astronomical spectrographs have a resolution ranging between a few hundred to 200.000. Deconvolution and correlation techniques are being employed with a significance down…
