There are now[1] almost %%(color:green;)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|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].
There are now (* as of 2008 Jun 25) almost %%(color:green;)325%% 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|http://solarb.mssl.ucl.ac.uk/SolarB/] (MSSL). This is a very powerful tool where you can not only look up a Study by its ID number, but also immediately access all the FITS files created by that study. That way you can take a look at the real data and see whether it's appropriate to what you want to do!
\\ \\ Alternatively you can use the [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].

[#1] as of 2008 Jun 25
To run the EIS Planning Tool, first ensure that you've followed the [guidelines for its set-up|http://solarb.mssl.ucl.ac.uk/SolarB/PlanningTool_v3.0.jsp].
To make sure that you're pointing at the official studies database (OSDB), first type
\\
{{{print,fix_zdbase(/eis)}}}
\\
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 \\
{{{eis_xstudy}}}
\\
There, you can look at the details of the rasters (i.e. component parts that make up a study).
Go to [EisXstudy] for a walk-through on how to use this interface.

__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).

Here is a recommendation for a low telemetry slot imaging study.
As of today, the estimated data rate is 13 KBits/s. Notice that compression is Q65.
{{{
Study 000292:
ACRONYM: IUU_SLOT_136x400_Q65
Slot imaging. Low data rate. Four 15s exposures at adjacent pointing
positions sampling a 136"x400" FOV in around 90s (there's a 5 second
delay after each exposure). 8" overlapping scan (40" Slot, 32" FMIR step size).
Spectral windows are selected for their spectral purity, diagnosed from
previous 40" observations. JPEG65 compression.
TARGET : Active Region (AR)
EXPOSURE TIME : 15s (+5s exposure delay)
SLIT : 40"
FOV : 136"x400"
SPECTRAL WIND. : 9
COMPRESSION : JPEG65
ESTIMATED CADENCE : ~90s
ESTIMATED DURATION : ~15m 41s (10 repeats)
Data rate : 10.39 kBits/s
Data Volume (per hour) : 37.4 MBits/h
WARNING:
None
}}}
Here are two examples of expected performance for Active Region (on top) and Quiet Sun (bottom) targets. These are animated GIFs of just a few frames. Reload page if movies are not running. The Fe XXIII spectral window is a blend of several lines. That line in particular is only significant at very high temperatures.
