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!

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.
