This page lists several typical examples of EIS studies created for use under the new Hinode data-volume management scheme, as well as information about operational restrictions and regular activities performed by EIS.

For general information on observing with EIS using the new antenna go over to our Wiki page on Observing with EIS and the S-band Antenna.



 
There are now[1] almost 290 studies (including science & engineering task) available to EIS observation.


The details of each study such as line list, winodw size, exposure time etc. can be accessed online at Hinode/EIS website (MSSL), or

alternatively you can use EIS planning tool, which is distributed within Solarsoft.
=>  Checking EIS planning tool user guides.

On the Hinode/EIS website there two especially relevant and useful webpages:

      This page lists all studies created so far for EIS observation, and enables user to view deatils of each study. When planning your own observation with EIS, it is recommanded to choose those suitable studies from the list directly rather than to design your own studies (unless been instructed to do so by EIS team).

Warning: EIS studies with IDs below #250 should not be used under the new Hinode data-volume regime!
      Tips: on this page user can click right-side button of each study to search the associated eis fits files (i.e. generated by that study) and have a quick look of thumbnails of the fits files. This may help user to choose the right study and check how the results (eg. intensity, velocity maps) obtained by the study probably like.


      This page is a summary of EIS as-run database. It shows how frequently and when a study was run by EIS. It would be useful when you'd like to search popular studies or simply check when/whether your study has been run.

      Tips: user can view the summary based on different targets such as Active Region (AR), Quiet Sun (QS), etc, and user can sort the summary by study ID or running times.

 


 
EIS Daily Plan can be accessed from DARTS website, where you may find lots of text files. These files just list EIS daily activities along EIS Observing Timeline.

EIS Weekly Observing Summary is a guidance of EIS science observation, decided by EIS team. EIS planner will make observing plan based on this guidance for the incoming week.

It is very usful if you'd like to check whether your proposal is on the schedule and when your observation will be run by EIS (roughly).
=>  You can click to access EIS weekly observing summary
 
 


 
On Hinode Daily Events Page, you can check all three instruments' (EIS, SOT, XRT) daily events.

One thing you'd probably like to have a look is DR allocation table. For example, on 2008/06/21 (Sat):
This will give you a roughly idea of EIS daily data volume.
 




Examples of EIS typical studies under the low data-volume restriction:



Active Region
  • PRY_footpoints_lite (Study 000241)

USAGE:
--------------------
If the contacts allow a period of high data rate, please supplement
this study with PRY_footpoints_v2.

As a context raster, please use PRY_slot_context (duration: 3min).
