SOPHIE cross-correlation filesSOPHIE science exposures are subjected to an automatic cross-correlation process using the spectral type information given in the relevant catalog entry. If no spectral type is specified, or none corresponds, it is correlated with a G2 mask. The CCF is ca lculated over a ±30 km/s interval and a gaussian is fitted to the profile of the strongest dip detected.
Results from this automatic fitting procedure should be treated with caution in the case of early-type or peculiar stars, where spurious values can result, such as highly negative velocities with large FWHMs. Failure is represented by rv = 999 km/s and FW HM = 0. In all cases a look at the CCF plot should quickly dispel any doubts.
The following CCF information is presented :
Future developmentShould become available : information about the velocity drift (for simultaneous Thorium exposures).
OHP data distribution policyAll data available from this Archive are the property of OHP (Observatoire de Haute-Provence). Access to SOPHIE observations is restricted to the original PI for a one-year period, but some large key programs are granted an extended (5-year) protection. Data benefiting from this extension are still released after a year, but in a modified form where the exact time of observation is truncated. All data will be available with time information unmasked after the 5-year period. This prescription also applies to CCF results.
