CoSEE-Cat

Tables

All the data in the CoSEE-Cat DR1 can be accessed through the following four tables:

  • the Overview table provides only the most essential information for all events in a concise way. This includes: event ID, electron onset time at EPD, timing and estimated GOES class of the associated STIX flare, and indications of the detection of EUV eruptive events, radio type III bursts, and CMEs;
  • the Main table lists all measurements that were derived from EPD, STIX, RPW and EUI data, as well as the Metis instrument status, and the outcome of the magnetic connectivity tool;
  • the Interplanetary Context table presents the conditions in the interplanetary medium as measured by the in-situ instruments on Solar Orbiter;
  • for events possibly associated with a CME detected with Metis, the details are provided in the table Coronal Mass Ejections.

For each table, a brief description of each column is displayed when hovering the mouse over the question mark next to the column name. This description is also displayed on the metadata page of each table, for example coseecat_dr1.overview. It is possible to limit the amount of events shown in every table by performing a quick search in the "Filter" field, for example to look for events on a given date. More complex queries can be executed by selecting "Query" in the top menu: this opens an interface where the data can be queried using the Astronomical Data Query Language (ADQL) or the Postgres flavour of SQL (Structured Query Language). Detailed instructions are provided in the Documentation > Query Interface page.

Each of the four table can be downloaded as a CSV file. The full DR1 with all parameters as listed in Appendix A of Warmuth et al. (2025) can also be downloaded from the CoSEE-Cat DR1 metadata page

Plots and event viewer

In all four tables, the first column gives the unique event identifier (event_id). This ID is associated with a link, which opens a pop-up window that displays the following:

  • a link to an event viewer, which displays all the plots available for that event, links to external movies (when available), and a sub-set of the most relevant data;
  • a link "Show all Data Links", which opens a new window with links to all available plots and external movies, when available;
  • up to five plots; a brief description of each plot is given below.

All plots for all events can be downloaded as a ZIP archive (~500 MB). Single plots can be downloaded from the links in the DataLink viewer.


Overview plot

Overview plot
Overview of EPD, RPW and STIX observations. From top to bottom: electron time profiles observed by different EPD sensors at selected energy bands between 10 keV and 1 MeV; Electron inensity for each energy channel shown as c/v versus time; RPW dynamic radiospectrum, showing a type III radio burst close to the electron release time; X-ray light curves observed by STIX in five different energy bands from 4 to 84 keV. The small insert at the bottom right shows the locations of STEREO-A, Solar Orbiter, PSP and the inner planets. The times indicated by the vertical lines are defined at the bottom of the plot.


EUI-STIX maps

Plot for EUI-STIX
Maps showing flare locations and magnetic connectivity. Left panel: Full-disk EUV image in the 174 A band provided by EUI/FSI. Overplotted are the flare locations derived from STIX and EUI, shown as blue and red circles, respectively. The green ellipse indicates the footpoint of magnetic connectivity provided by the IRAP tool. The size of the ellipse reflects the uncertainties in longitude and latitude. The purple arrow indicates the central position angle of a possibly associated CME observed by Metis. Right panel: X-ray source reconstructed from STIX data with the EM algorithm.


EPD anisotropy

Plot for EPT anisotropy
Aniostropy plot, derived from EPT data. Top panel: 35.6--58.8 keV electron intensities (solid lines) as observed by the four telescopes. The dashed lines show the modelled background intensities during the time interval of interest. The selected background interval is shaded in grey. Second panel: The pitch-angle ranges covered by the telescopes. Third panel: 1st-order anisotropy for the measured electron intensities without (black line) and with background subtraction (magenta line) with the 95% confidence intervals shaded and the peaks denoted as the black and the magenta dots, respectively. The dark gray shading at the top and bottom boundaries denotes anisotropy values that cannot be observed with the given pitch-angle coverage. Bottom panel: 0.349--0.412 MeV ion intensities as observed by the four telescopes. The black vertical line denotes the event onset time.


RPW-STIX plot

Plot for RPW-STIX
Combined RPW-STIX plot. Top panels: radio flux in solar flux units (SFU) versus time and frequency measured by RPW/TNR and RPW/HFR. Bottom panel: X-ray flux in counts per 4 sec as measured by STIX. Dashed vertical lines indicate the following times: electron solar release times (SRT) derived from EPD data by time shift analysis (TSA, red) and velocity dispersion analysis (VDA, cyan) methods, time of maximum X-ray flux from STIX (blue), and RPW onset times (balck), detected at 4 MHz or 1 MHz. Horizontal shaded areas at the top of the bottom panel indicate the uncertainties of the TSA and VDA SRTs following the same colour code.


Interplanetary context

Plot for IP-context
Conditions in the interplanetary (IP) medium during a time range from one day before until 2.5 days after a SEE event. The vertical dashed line indicates the electron onset time. From top to bottom: solar wind proton speed, proton density, proton temperature, IP magnetic field magnitude accompanied by its polarity (red, negative; green, positive; yellow, ambiguous), Radial-Tangential-Normal (RTN) magnetic field separated components, magnetic field azimuthal angle in the coordinate system complemented with the two possible nominal Parker spiral angles (red, negative; green, positive. Derived from proton speed), IP magnetic field latitudinal angle, and total pressure.
