Functionality
GAUDI, the COROT Ground-Based Archive System, provides the following
functionality to the end-user:
-
Data access form
-
Visualisation of spectra
-
Data retrieval: spectra and photometric indices
-
Retrieval of multiple spectra, with choice of compression
schemes
-
On-line access to project documentation
Archive Searches
Queries are made by means of a fill-in form, and permits query by
object name (or list of objects), coordinates, spectral type, instrument or photometric indices.
Four output formats (HTML, ASCII or
as tab- or comma-separated values) can be selected. The output fields (Spectroscopy, Photometry) may be
ordered by coordinates, object identification, and spectral type. An on-line description of each archive search-keyword is available via links embedded
in the query form.
Data Products
The server stores:
- Spectra
- Spectra of the average photospheric profiles
- Full echelle spectra.
- Dereddened photometric indices: beta, m0, (b-y)0, c0
Spectra are delivered as FITS files, and can be
imported into standard image processing packages such as
IDL, IRAF and MIDAS.
Data Retrieval
In the HTML output format, links are provided to plot and
download individual spectrum. Groups of spectra can be retrieved,
with group selection
defined according to file type ( Average or Full), or
fine-tuned by marking individual spectra. On-line descriptions of
each output column and of
data retrieval are
available via embedded links in the output form.
