8.2.3 Use of archived HARPS-N data
For convenient archiving of raw observation data and pipeline products dedicated Data Archiving
software is available at Trieste Science Archive. It allows the observers to get the observations data,
choosing the data product they want (raw data, reduced data or both, log files).
HARPS-N data can be requested from the Trieste Science Archive:
http://ia2.oats.inaf.it/index.php/tngarchive/tng
Data taken by observers in Visitor or Service Mode are subject to the usual proprietary period of 1
year.
According to the Agreement between GTO consortium and the HARPS-N Consortium the data
taken by the Consortium during their Guaranteed Time are subject to special protection:
• Raw data and reduced spectra (I=f(λ)) in the Earth reference frame at the time of the
observation will be made public one year after observations
• All raw data and radial velocity measurements obtained by the Consortium will be made public
one year after the end of the 5 year Guaranteed Time period.
In practice this means that data obtained by the Consortium can be requested from the TNG
Science Archive as usual one year after the observations. However, in order to make recovery of
precise radial velocities impossible, the keywords containing information about the exact time of
the observations will be filtered from all file headers (raw and reduced) by the Archive during the
de-archiving process. This filtering will be applied until one year after the end of the 5 year
Guaranteed Time period.
