Elodie archive Help

The ELODIE archive hosts all the spectra produced by the ELODIE spectrograph used at the 1.93 m telescope of Observatoire de Haute Provence.

The spectrograph was used from 1993 through August 2006 and the database contains more than 31000 public spectra (chosen with S/N(550nm)>10) of astronomical interest which can be freely pre-viewed or downloaded from the archive.

There are 4 methods to access to the database:

  1. Search by designation, around a designation or around a position in a pre-defined sample or in the whole catalogue:
    The identifier can be a conventional name (for example: HD141569, HIP062384, GJ719, VEGA, RR LYR, MOON) or a name to be resolved into a position by simbad (ex. simbad:vega). It is also possible to enter a short list of designations separated with comas or a part of a name, like GJ%, where the % will match any characters.
      The identifier can also be a position (ex. J17:28:50.1 +00:19:15 or J154958.1-035515). In these latter cases the search is made around the given position.
    If the equinox of the coordinates is not specified, then the B1950 coordinates are used.
    If the request is made around a designation or a position, the user should choose the field radius, otherwise, the default radius is of 10 arcmin around the specified designation.
  2. Search within a region of the sky in a pre-defined sample or in the whole catalogue.
    The region of the sky consists in an interval of right ascension (RA) and declination (DEC) written in free format, for example:J hh mm ss and +dd mm ss (if the coordinates equinox is not specified, then the B1950 coordinates are used). If no region is indicated, then the whole pre-defined sample or the whole catalogue will be listed.
    Note: The coordinates are automatically transformed to epoch B1950 and the search is made inside the transformed box.
  3. Search by multiple contraints
    Constraints may be defined on the designation, position, signal-to-noise ratio, date of observation, name of observer and program number.
    These constraints may be given as lists or ranges (lower and upper limits, if the lower limit is not set it means: less than upper limit, and if upper limit is not set, the meaning is: greater than lower limit).
    Constraint on designation may be like: GJ%,vega.
  4. Search from a user's provided list of objects
    A list of designation, with one name per line, may be uploaded from a file (example).
    Short coma-separated lists may be entered in the 'designation' field of the search by designation menu.
Two pre-defined samples are available at present:
  1. The whole catalogue
  2. The sample of stars for which the metallicity [Fe/H] has been measured in Cayrel de Strobel et al. (1997). This sample contains 6422 stars.
A query leads to a listing of all spectra corresponding to the request. Each row of the list contains the following fields: More detailed explanations are given in the help links located on top of each column. The user can accede to these links from the top of this page as well.
Below the list of observations a menu proposes, when relevant, to extend the search to the vicinity, to sort the list according to some key (right ascension, signal to noise ratio, date) or to filter the list by applying additional constraints on some parameters.
This archive is actively maintained. We thus welcome feedback from the user to help us detect anomalies and improve the website.
