EIS Mapper


EIS mapper is a way of showing the locations of EIS rasters on full disk images of the Sun (see example to the right). For each day of the mission, the image (usually from the AIA 193 channel) is shown with boxes overlaid to show the locations of the EIS rasters. On the right side of the screen the complete list of EIS observations for that day is shown. Below the image a GOES X-ray plot is shown.

Links at the top of each EIS mapper page allow you to quickly move to previous and next days, and there is also a link to the calendar for the entire year.

EIS mapper results for complete EIS mission

Please check EIS mapper software for how to create the web-pages and how to customize the observations that are shown.

Customized EIS mapper results

The links below show EIS mapper results for sub-sets of the EIS data:

Spectral atlas data (AIA 193 images)
Spectral atlas data (AIA 171 images)
The "cool_loop" rasters
The "HPW021" rasters
The "pry_flare" sit-and-stare studies for flare observations
The "el_dhb" studies (Fe X magnetic field measurements)

These pages were also generated with the EIS Mapper software but using filters, as described on the EIS Mapper software page.

Additional notes

  • Blue boxes denote narrow slit EIS rasters; yellow boxes denote slot data.
  • The routine has the following priority for choosing images: AIA 193, EIT 195, XRT Ti-poly and MDI magnetogram. Note that AIA starting taking images around May 2010.
  • Flare positions and classes are taken from the XRT Flare Catalog. This catalog is updated only periodically, so flare data may not be available for the most recent 6-12 months.
  • Pointing information for the EIS rasters is obtained by querying the Oslo data archive to return "xcen_corr" and "ycen_corr". These are generally more accurate than the xcen and ycen values stored in the EIS database.

Making a local copy

You can make a local copy of the EIS mapper files using wget. This allows you to click between days more quickly than possible through an internet connection.

To copy the spectral atlas files, for example, do:

> wget -r -np -nH https://eismapper.pyoung.org/atlas/html/

The complete set of EIS mapper data takes up about 3 GBytes (as of 2020).

Known issues

  • The boxes for the "JTM" studies during 2006 and early 2007 are not accurate.
