This page lists several typical examples of EIS studies created for use under the new Hinode data-volume management scheme.
If you want more general guidance about operational restrictions on observing with EIS using the new antenna, then just go over to our Wiki page on Observing with EIS and the S-band Antenna.
There are now[1] almost 290 pre-defined studies (including both science and so-called engineering studies) already available if you want to make observations with EIS.
The details of each study, such as line list, window size, exposure time, etc. can be accessed online at the Hinode/EIS website
(MSSL), or alternatively you can use the EIS planning tool
, which is distributed within Solarsoft.

The easiest thing to do is to look up a study the website. But to look up a study in SolarSoft just to use the command

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.

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 rough idea of the allocated EIS volume for a three-day plan.

Examples of EIS typical studies under the low data-volume restriction:
Active Region
- PRY_footpoints_lite (Study 000241)
Study 000241: ACRONYM: PRY_footpoints_lite Objective: -------------------- This is a variation on the study PRY_footpoints_v2 designed for periods when EIS has a *low data rate*. The study has a wide range of lines and diagnostics and is suitable as a general purpose AR study. Study summary ------------------- TARGET: Active region EXPOSURE TIME: 30s SLOT: 2" Raster Type: Scan FOV: 100"x240" ESTIMATED CADENCE: 28m16s Compression: DPCM DATE Volume: 53.38 Mbits Spectral Lines: FeX,184.33;FeXII,186.75;FeXI,188.35;FeXXIV,192.01;CaXVII,192.82;FeXII,195.00;FeXIII,202.04;FeXIII,203.83;OV,248.46;HeII,256.40;FeXVI,262.98;MgVI,268.99;FeXIV,274.20;SiVII,275.35;MgV,276.58;MgVII,278.39;MgVII,280.75;FeXV,284.16 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). WARNING: None
