Introduction to the SOPHIE ArchiveThe SOPHIE Archive gives access to the observations obtained with the spectrograph since it started operations on 24 August 2006. Data enter the database one day after they are obtained. In its present version the database will produce, upon interrogation, a list of all existing observations for a given object or list of objects together with pointers to the extracted (e2ds) and reconnected (s1d) spectra, cross-corelation functions and radial velocity measurements, if public.
The above data are produced by the standard data reduction pipeline, executed immediately after the acquisition of the science exposures. The corresponding raw data can be downloaded as large tar files, containing all the observations and calibration taken in a given night.
OHP data distribution policyAccess to SOPHIE observations is restricted to the original PI for a one-year period. However, some large key programs are granted an extended (5-year) protection. Spectra benefiting from this extension are released after a year, but in a modified form where the exact time of observation is truncated. The data will be available with all time information unmasked after the 5-year period.
Use of data retrievedThe data in the SOPHIE archive are made freely available to the astronomical community but remain the property of the Observatoire de Haute-Provence (OHP). Any organized re-distribution of the spectra retrieved from the archive is unauthorized. Commercial use is strictly prohibited without our prior agreement.
Publications based on data obtained from this archive should be accompanied by the statement: "Based on data retrieved from the SOPHIE archive at Observatoire de Haute-Provence (OHP), available at atlas.obs-hp.fr/sophie". The paper "The ELODIE Archive" by Moultaka et al. (2004) PASP, 116, 693 could be added to the bibliography, but is not required. A list of papers based on SOPHIE data is available.
Available information on spectraThe column headings on a query results page on spectra give the following information :
Spectra are shown in order of increasing right ascension and then of sequence number (chronological order). At the present time, a simple way to list them by observing date is to replace in the URL the string "&ob=ra&" by "&ob=date&". See the instrument web page for more information and specially the data products page for a complete description of all files.
Available information on CCF results
FITS extensionsSpectra of the second fiber (sky or Th-AR spectra) are included with the reconnected rebinned 's1d' spectra and with the extracted 'e2ds' spectra as FITS extensions. The 'e2ds' spectra also include extensions for the associated 'wave' and 'blaze' calibration files.
Advanced ways to access the ArchiveIf users need to download a large number of FITS files, details are given on the possibility of using direct access to the observation catalog, to 's1d' and 'e2ds' spectra and to 'ccf' files.
Flux calibrationAt the present time SOPHIE spectra have a provisonal flux scale which is relative to the tungsten lamp, but the over-all instrumental flux modulation retains the characteristics of the uncorrected spectrum. In addition, 's1d' reconnected spectra suffer from a residual "echelle ripple" effect, amounting to 5 % in the HE and HR modes, corresponding to an undercorrected blaze function.
Object designationsThere are currently over 7500 distinct object designations in the database. We are continuously searching and correcting mis-identifications, as part as the curation effort.
Any remaining errors should be reported to the database team.
