SOPHIE Spectrograph public-domain dataCommissioning and Science Demonstration observations24 August - 17 October 2006
First light was officially achieved on 31 July 2006.
Data obtained on 31 July - 6 August 2006 and 21 - 23 August
are not listed here as the first wavelength solution was obtained only on 24 August.
First observations by visiting astronomers started on 28 August.
The telescope mirrors were aluminized on the second week of September, so exposure times for the four
August nights are not representative of the instrument throughput.
On many nights there have been long series of exposures of a given star, but
in such cases only one spectrum is listed here unless there was a change of
spectral resolution (between modes HE and HR). Click on a date for a full listing of that night's
observing log. If necessary, typing the full URL for that night (for example:
comm/raw/2006-08-24/ or
comm/reduced/2006-08-24/) will
result in a
complete list of all files in that particular directory. No CCF files
are shown for stars with O, B or A types. Please refer to
the
Data Products page for information on the various types of reduced
files.
Warnings : Exposures made in the simultaneous Thorium HR mode, labelled as HR*, show
contamination by ghosts due to internal reflections from very strong Argon lines, mostly redward of
7000 Å. These are now suppressed since 10 April 2007,
when a special high-pass interference filter was installed in front of
the Thorium lamp. A bug in the reduction software has resulted in an error on the time of
mid-exposure, and consequently on the barycentric radial-velocity correction, which were calculated
one exposure time later. The reconnected spectra, which include the
barycentric correction are thus also affected. This
bug was corrected on December 26. The 's1d' reconnected spectra
obtained in HE mode show a 5% residual blaze function modulation.
The data presented here were processed by an early version of the on-line DRS pipeline.
A new release is planned after all data are reprocessed.
