In its definite form (SpaceInn deliverable D3.10), the archive will have an user-friendly interface that will allow several kind of queries (by target, by variability, class, by spectral type, and so on).
The reduced spectra along with activity indices, physical parameters and other indicators are already available to the public (SpaceInn deliverable D3.8) on an extra dedicated website (please click here).
In total there are 7103 spectra of 261 targets observed with the HARPS spectrograph during the Large Programmes LP 182.D-0356 and LP 185.D-0056, spanning over nine semesters, from December 2008 to January 2013, for a total of 135 nights of observations.
The spectra were taken mostly as complementary observations to the photometric light curves of many of the asteroseismological targets of the CoRoT satellite. A certain number of them pertain instead to other, non-CoRoT targets: these objects were observed in order to better characterize the variability classes of the CoRoT targets.
We provide a tarfile for each observed target. The tarfiles contain the spectra in two different format (both reduced, calibrated and converted in VO-compliant fits files, but the first with the echelle orders separated and the flux both normalized and unnormalized, and the second with the echelle orders merged and only the normalized flux), the mean line profiles of each spectrum, a fits table with a general overview of the object time series, two postscript files (one that will allow a quick look at the pulsational content of the time series, while the other is a comparison between the observed spectra and the best-fit synthetic spectrum obtained with SME), and a readme file.
All the relevant information (physical parameters, activity indices, Halpha emission index, radial velocity, projected rotational velocity, and so on) are stored in the headers of the fits files.
A more detailed description of the work done in reduceing the spectra and computing the indicators and the physical parameters can be found in the report on the D3.8 deliverables. –> link to the pdf-file of the report
The future works of WP 3.3 will consist of the generation of simultaneous spectroscopic and photometric time series (D3.9, only for the CoRoT targets), and the creation of an online VO-compliant database, where all the data will easily be retrieved and viewed (D3.10).
