Bright stars spectrographic observation series
Rigel (Beta Ori)
RA: 5H14.5M - DEC: -8°12' (2000,0)
Latest update: April 10, 2009
Instrument: 0.28 m telescope (Celestron
11) + eShel spectrograph (R=11000) + QSI532 CCD camera (CCD KAF3200ME)
Observatory: Castanet-Tolosan (France)
Observer: C. Buil
Processing: standard échelle pipeline (Reshel software V1.11). H2O telluric lines are removed (division by a synthetic H2O spectrum by using Vspec software - the telluric lines list is from GEISA database (LMD/CNRS)). The diurnal and annual earth velocity are corrected (the spectra wavelength are given in an heliocentric reference for a standard atmopshere). For the plots, the continuum is normalized and vertically shifted between each spectrun for clarity. Date are given in UT.
