Reduced data available for public download
Description of the data available in the public releases The HC-DC (previously SPHERE-DC) aims at providing a full reduction of all public SPHERE data. Given the huge amount of data, we spent several years developping a fully automatic pipeline that provide good reduction in most cases. It works well for typical SPHERE science cases (exoplanet/disc imaging, high contrast extended source) (...)
Data access
We provide access to reduced public data in two different ways, depending on the data level : at the SPHERE processing center in Grenoble for the first levels (data levels 0-2), and and through the DIVA+ data base in Marseille for the most advanced data products (SPHERE and other instruments). The first access is data-oriented (ESO archive-like) while the second access is more target-oriented (...)
Request for data processing
Procedure to request data reduction : We perform reduction on request based on the pipeline already implemented for the processing of public data. We accept requests from the PI or CoI of an observation (no reduction otherwise, except with the PI explicit agreement). Send an email to sphere-dc-req at univ-grenoble-alpes.fr, copy and fill the form below : SHC-DC data reduction request form (...)
How to acknowledge the Data Center
Acknowledgements in your publications if you use SPHERE reduced data : This work has made use of the High Contrast Data Centre, jointly operated by OSUG/IPAG (Grenoble), PYTHEAS/LAM/CeSAM (Marseille), OCA/Lagrange (Nice), Observatoire de Paris/LESIA (Paris), and Observatoire de Lyon/CRAL, and supported by a grant from Labex OSUG@2020 (Investissements d’avenir – ANR10 LABX56).

FAQ
FAQ Please do not hesitate to contact us at sphere-dc-req at univ-grenoble-alpes.fr is you have any questions. SPHERE-DC has now become the High Contrast Data Centre (HC(DC). How to browse and download data from the HC-DC client ? You need to click on the java client link to install the HC-DC client (link is : (...)
Client launch
Before accessing and retrieving SPHERE data from our Processing Center : You need to launch our Sphere client to be able to browse and retrieve data. You need it to install it once and then it automatically updates to include the new developpements at HC-DC (previously SPHERE DC). The download links and procedure are described here : http://sphere-dc.osug.fr/sphere-server/ To browse (...)
