July 18.97, 2003 observation (magnitude V=11.3)

Observatory: Pic du Midi Observatory (France)
Observers: André Rondi, Sylvain Rondi, Valérie Desnoux, Christian Buil
Instrument: 24-inch telescope + LORIS spectrograph at the spectral sample of 8 A/pixel + Audine KAF-1602E CCD (bin. 1x1)
Processing: Iris & VisualSpec software

Note: (1) Two set of exposure are merged for visible and IR part of the spectrum. (2) The instrumental response is corrected but intensity is relative. (3) The continuum is normalized at the wavelength 6690 angstroms.
