1. Data archive

The VLT/SPHERE data can be fetched from the SPHERE raw data query form. For example, if we want to download the data taken with the project 096.C-0248, we can enter 096.C-0248 in the Program ID section and then click Search. You can then mark the observations you want to download by checking the boxes on the left of those rows, and then click Request marked datasets.

2. Pipeline installation

We can perform pipeline data reduction using the https://irdap.readthedocs.io/en/latest/ python module. You can simply install it with pip wheel, which is instructed https://irdap.readthedocs.io/en/latest/installation.html.

To make sure you installation is successful, you can follow the https://irdap.readthedocs.io/en/latest/example.html to run the demo data reduction. It calibrates the data taken with the project 096.C-0248. You don’t need to download the data. But you can try to download the same data from the archive following the instruction in Section 1, and then follow the instruction in Section 3 to see if you can get the same images as what are given by the demo.

3. Running pipeline

It is pretty simply to run the IRDAP pipeline. Please follow the instruction here.
