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.

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.
