We perform reduction on request based on the pipeline already implemented for the processing of SPHERE public data. We accept requests from the PI or CoI of an observation (no reduction otherwise, except with the PI explicit agreement). It typically takes a few days up to a week to answer your request depending on our availability.
To do so, send an email to hc-dc-req at univ-grenoble-alpes.fr, copy and fill the form below. It is also useful if you add a few lignes to explain your science case so that we can adapt the reduction if needed/possible.
| Name | – |
| Institute | – |
| Name of PI (agreement needed) | – |
| Run ID | – |
| Numbers of nights/hours to reduce | – |
| Observing modes used | – |
The procedure is then the following (more details on our processing protocol page) :
- The HC-DC team retrieves your data, with two possible procedures:
- First option : you fill the ESO form on your ESO account allowing the team (indicate the account SPHEREDC, hc-dc-req at univ-grenoble-alpes.fr) to allow us to access the relevant data
- Second option : you deposit your data and on-line space where we can retrieve it
- The data is reduced by the HC-DC team
- You are given access to the reduced data (protected by password) and inputs on these results using a download script
- If necessary other exchanges on the quality of the reduction and/or data can follow.
- Do not forget to look at the acknowledgment page !
The HC-DC team provides a service: as such, the team will guarantee confidentiality of private data and does not request to be co-author of the publications. The team may however use some metadata to insure at best their instrument monitoring mission, and more specifically the calibrations files.
How are your data reduced?
The codes used to reduce your data and available algorithms are described in the list of available data.
In addition, we can run on demand ASDI-PCA (IFS data): we run a PCA analysis using both the time and the spectral dimension to build the reference image which significantly increases the detection limits. We can also use on demand others algorithms on your favourite dataset.
We can also manage reduction of data obtained in star-hopping mode for IRDIS, running classical RDI and TLOCI-RDI algorithms. IFS star-hopping mode is not supported yet to this stage, but we do provide level 1 data.
Please do not hesitate to contact us at hc-dc-req at univ-grenoble-alpes.fr is you have any comment, specific needs or suggestions on the released data, or if you notice any issue.
Access to our application to process your data
You can also reduce your data using our client and the public tools that are implemented.
- Follow the above procedure so that we can import your data into your dedicated workspace.
- An account will be created for you
- You access the server and process your data
- You retrieve your data
- If necessary other exchanges on the quality of the reduction and/or data can follow.
