There are almost %%(color:green;)290%% stuies (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|http://msslxr.mssl.ucl.ac.uk:8080/SolarB/] (MSSL), or \\ \\ alternatively you can use [EIS planning tool|http://sohowww.nascom.nasa.gov/solarsoft/hinode/eis/idl/planning/], which is distributed within [Solarsoft|http://www.mssl.ucl.ac.uk/surf/surfsolarsoft.html].

This page lists %%(color:green;)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
Warning: EIS studies with IDs below #240 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 %%(color:green;)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 (%%(color:green;)AR%%), Quiet Sun (%%(color:green;)QS%%), etc, and user can sort the summary by __study ID__ or __running times__.

__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).

On [Hinode Daily Events Page|http://www.isas.jaxa.jp/home/solar/hinode_op/hinode_daily_events.php], 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):
[{Image src='images/study/1229_d.png'}]
This will give you a roughly idea of EIS daily data volume.

Examples of EIS studies under the low data-volume restriction:
* PRY_footpoints_lite (Study 000241)
{{{
Study 000241:
ACRONYM: PRY_footpoints_lite
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.
TARGET: Active region
EXPOSURE TIME: 30s
SLOT: 2"
FOV: 100"x240"
ESTIMATED CADENCE: 28mins
DATE Volume: 53.38 Mbits
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
