Our data products can be accessed by three methods, which differ in terms of functionnality and data perimeter (green=available, orange=soon available).
The DIVA+ data base allow you to access two types of data: i/ the highest levels of our SPHERE reductions (perimeter and data type list), detections limits, contrast curves, detected candidates … ii/ as well as many homogeneous surveys obtained with different instruments. Our new user-friendly interface allows multi-parameter requests (target name, date, instrument…) to download the data in HCI-FITS format, access via API, as well as access to any whole survey in one click..
- Access to the data : DIVA+
- DIVA+ documentation
- Ackowledgements and mandatory references
Our processing center also allows to retrieve all data that have been processed by the HC-DC team. This includes the SPHERE data already available on the DIVA+ portal, but also data cubes and reduced calibrations (perimeter and data type list). You can search for data based on multi-parameter requests (target name, date, instrument…) and download the data either directly (for single files) or through a script file. You will need to install our client (once installed, it will automatically update to include the new developpements at HC-DC). You will access all public releases with login = public_user and password = public_user.

We have started to upload some of our SPHERE reduced data into the ESO reduced data archive.
The science products in the SPHERE data collection on the ESO archive are single reduced image files (one per observation) processed either using cADI or non-ADI. The first data products published in December 2022 in the ESO Science Archive Facility include imaging data from the IRDIS sub-system, observed during the ESO period P103 and P104, acquired between April 2019 and March 2020, where followed by many IRDIS data obtained during ESO periods P95-P102 (acquisition starting in April 1995). More will be released soon, stay tuned!
For users interested in getting either more aggressive reductions that reach a better contrast (at the cost of a reduced sensitivity to extended signal such as circumstellar disk signals), or for users interested in getting the master cubes (pre-processed data cubes of images, centered, bad-pixel corrected, flat-field corrected, anamorphism-corrected and background subtracted) to perform their own post-processing, the data are available from DIVA+ data base and the processing center client listed above.
