Web interface in the HelioPhysics Archive (HPA) 

Welcome to the user guide for the web interface of the Solar Orbiter ARchive (SOAR) data in HPA. This graphical user interface (GUI), version 0.2, is the first beta version of this GUI, beta at it does not yet provide all functionalities of the current operational SOAR. But as we will see it provides new important functionalities.

Accessing the SOAR web interface in HPA

To access the SOAR GUI in HPA, connect to https://hpa.esa.int
click on the Solar Orbiter tile and then on Data.

 

Search Panel

The Search panel is located on the left of the interface and allows you to select among the following search fields (all of them are optional) to search for public science files 

  • A time range
  • Specific instruments
  • Processing level
    • Level 3: value-added datasets
    • Level 2: calibrated
    • Level 1: uncalibrated/engineering units (i.e., counts for particle instruments)
    • Level 0: decommutated telemetry
  • Filename
    • to search for specific type of filenames, any text can be put into this box and will be treated as a case-insensitive text search with wildcards (*) either end (? can be used as a single character wildcard) of all the filenames, e.g., ‘HRI’ or ‘swa-eas-padc_20220925T052734’
  • Solar Orbiter Observing Plan (SOOP)
    • All SOOPs are given a long name and a short name (type). This dropdown box will allow one SOOP to be chosen and all data observed stamped in the data with that SOOP will be returned. Note that it is only applicable to remote sensing instruments. 
    • Full information on SOOPs
  • The Search and Clear buttons to start the search or to clear all the criteria, resp.
  • Inactive files: only applicable to old EUI files, see info box

Note that by default, each field is set to 'All', and so an empty search will return all the latest active files. All these fields are explained in more details in the info box (i) next to them.

Results Display

Download buttons: to the top right are two buttons: “Download selected” and “Download all”.

File listing


 

  • Tickbox
    • Tick the box to select the file/product. Those selected can then be downloaded with the “Download selected” button.
  • Item Id
    • The item ID, or ‘data_item_id’ (see table access) refers to each individual product, and is the main identifier of the product.
  • Download icon
    • The single file can be downloaded directly with this icon.
  • Quick looks: Icons, Thumbnails, Postcards
    • If available (currently EUI L2 products), an icon will show that this product has a quick-look image. Hovering over the icon will show a larger version (the ‘thumbnail’) and then clicking on it will reveal the postcard. This postcard is in .png format and can be downloaded, but it is only meant as a representation of the data and each postcard uses the full dynamic range of the image (so no good for a movie) and of limited resolution.  See screenshots below.
  • Level
    • I.e., Processing level, as explained for the Search box.
  • Descriptor
    • This is the identifier of the type of data in the product.
  • Begin time
    • Time at the start of the observation, in ISO format, as given in the filename and the internal metadata (DATE-BEG).
  • End time
    • Time of the end of the observation, as given in the filename (if provided), in the internal metadata (if provided), or in the case of FITS files and DATE-END is not provided, it is calculated from the start time (DATE-BEG) and the centre time (DATE-AVG).
  • Instrument
    • The main instrument name.
  • Sensor
    • If a separate sensor exists (depends on the processing level, e.g., inboard sensor (IBS) and outboard sensor (OBS) are available at L1, but not L2) it will be given here.
  • File size
  • Archived on
    • Date that the file was ingested into the archive.
  • File format including CDF and FITS

Quick look images

The EUI L2 (fully processed data) results come with a series of images as quicklooks: smallest 'icons' in the results table rows - hover over this to display a slightly larger 'thumbnail':

and clicking on this will bring up a larger 'postcard' which can be downloaded as a PNG. Note that the quality of this quick look image is not of publication quality, and all use the full range of brightness from each individual file, and so not suitable for assembling a movie. Please use the L3 JP2 files for the consistent dynamic range.
