The SOPHIE Archive
SOPHIE Archive News
- For very accurate radial velocities (2 m/s) a
correction should be applied (available from 2011 through 2018).
Users are encouraged to use this file in order to correct for instrumental drifts that are not monitored by the calibration lamps.
Refer to Courcol et al. (2015) and Hara et al. (2020).
A RV Master constant file in HE mode will be available soon.
- One hundred SOPHIE spectra taken in September, October and December 2006 and February, September and October 2007
have been found to be affected by an inexact barycentric correction (found in the keyword OHP DRS BERV) due to a missing
decimal point in the catalog declination (found in the keyword OHP TARG DELTA).
Users wishing to recover accurate velocities for these observations are encouraged to re-compute the barycentric corrections.
Remember that the s1d reconnected spectra have also undergone this inexact barycentric correction.
- As of 22 March 2017, the ELODIE Archive interface has been upgraded and
now presents the same search options as the SOPHIE Archive. This allows to
search both Archives using SQL constraints on any of the displayed metadata
- Starting June 2015, the SOPHIE and ELODIE Archives are hosted on a new
machine (DELL PowerEdge R620, running Debian Linux, coupled to a PowerVault
MD1200 raid array) installed in the recently refurbished OHP server room.
This new configuration offers more than twice as much storage (now nearly
10 Tb) as the old system (Apple G5 Xserve + Xraid, running MacOS Server)
dating from late 2005.
- On 20 March 2014, the full SOPHIE database came back on-line after a major
problem with a partly corrupted internal RAID-1 disk array holding the operating system,
the users and the applications. Everything has been succesfully recovered from our backups :-)
- A query using object identifiers not resolved internally is now
handled correctly : the corresponding position is found using Simbad
and a search in a 1-arcmin cone around these coordinates is made on the
- An option is available to view and search with the original 'target_name' as
well as the target visual_magnitude and spectral_type present in the observer's
catalog. Users should be familiar with the SQL query
language to set constraints on multiple parameters.
- Calibration files (wavelength scale and blaze) associated with an
extracted 'e2ds' spectrum are now included as
extensions of the 'e2ds' FITS
file. This applies as well to the 'e2ds' spectra of fiber B.
- Spectra for fiber B (Sky or Thorium-Argon) are now systematically
included as an extension of the 's1d' FITS
- Read the
instructions on how to retrieve spectra directly with
wget. The interface now offers automatic generation of all the
wget commands needed to retrieve the results from a query.
- Details on the parameters listed after clicking on the "search CCF" field.
- Details on the parameters listed in
the spectrum query results page.
- As of early March 2014, there were more than 71200 spectra for 5230
distinct targets. Almost 37500 spectra are fully
public and more than 28000 spectra are available with
the exact time of observation masked (for
a 5-year period), while nearly 4900 spectra are under the
standard 1-year embargo.
- An updated "To Do" list is available.
- A list of refereed publications based on original SOPHIE data is maintained.
