    General advice

    As a general rule, please select the L2 processing level (best calibrated) version, available for all experiments but STIX (as of July 1, 2024). This will avoid the results containing other (uncalibrated) versions of the files. Note that a few instruments have higher-level L3 (derived) products (e.g., EUI JPEG 2000 images). One sub-instrument, SWA Heavy Ion Sensor (HIS), recommends to use its L3 data products as their best calibrated product.

    Search by telescope or sensor

    The SOAR web search interface (https://soar.esac.esa.int/soar/#search) enables the selection of multiple Solar Orbiter instruments with a dropdown box. However, there is not yet a capability to directly select a particular telescope (e.g. the Full Sun Imager -FSI- or the High Resolution Imager -HRI- for the EUI instrument) or sensor (e.g. PAS, EAS or HIS for SWA).

    To search for a particular sensor, please use the "File Name" field of the search interface. This has to be done one by one, but is case-insensitive and can involve strings with multiple (*) or single (?) character wildcards, e.g., 'epd-*-rates'.

    Search by cadence and/or reference frame

    A number of experiments propose different cadence for their measurements (e.g. MAG, EPD, STIX). Some scientific investigations require the highest cadence to perform certain data analyses, while others require a better data coverage. To select only these files, the Filename field can also be used to filter the descriptors of the filenames. Here are a few examples for EPD and MAG of single strings to input the "File Name" field (similar to the snapshot above).

    Solar Distance

    The SOAR graphical interface allows you to search by solar distance. Simply input a range of distances, between 0.29 AU and 1.02 AU, where you would like to restrict your search. This will result in a list of files corresponding to measurements performed by Solar Orbiter within that range. Be aware that this may result in one or more time periods when Solar Orbiter was flying through that distance range. As of July 1, 2024, the list of time ranges deduced by SOAR is not yet provided as a separate files but it is foreseen in the near future.

    For instance, there are two time periods in 2022 when Solar Orbiter was closer than 0.5 AU from the Sun and where MAG was operated:
    March 8 to April 16 and 23 September to end-October. Performing this search will extract daily files from MAG measurements during these two time periods in one go.

    This capability can also be used using the programmatic access using the Table Access Protocol. For instance, 

    to download all MAG 1 minute resolution files measured in 2022 up to 0.50 AU, i.e. 78 days spread over  08-Mar-2022 to 13-Apr-2022 and 24-Sep-2022 to 30-Oct-2022
