Collecting Data

Before you can reduce SOXS data, you will first need to download the data from the ESO Science Archive Facility (SAF). As a first step, navigate to the SAF query interface and enter the details of the object dataset you want to download. Add the target’s name and, optionally, the night the data was acquired. Select SOXS under the Spectroscopy column (and Imaging if required) and check ‘Science’ under the Category section (see Fig. 4). Now, click the green ‘Search’ button.

Now, click on the ‘MarkAll’ button and then ‘Request marked datasets’ (see Fig. 1).

Collecting the associated raw calibration frames with the raw science frames is essential. Otherwise, the pipeline will not be able to reduce your data. To do this, click the ‘Run association’ button beside the ‘Associated raw calibrations’ checkbox (shown in Fig. 2). Once the association is completed, the ‘Associated raw calibrations’ checkbox should be checked.

Finally, click the ‘Download ZIP file’ button.

The data will be collected in an ‘archive.zip’ archive, which can be uncompressed with the ‘unzip’ terminal command or typically by double-clicking the archive in your machine’s file browser.
