The page lists information of EIS study (observing sequences) and several typical examples of EIS study under the new Hinode data-volume regime, and the information about operation restrictions and regular activities by EIS.
- There are almost 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
(MSSL), or alternatively using EIS planning tool which is distributed with Solarsoft. Checking EIS planning tool user guides here.
- On Hinode/EIS website there two useful webpages especially:
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).
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.

- EIS daily plan can be reviewed from DARTS website
- This Hinode Daily Events Page can let you check the previous DR allocation (data volume on board?) for EIS. This will give you a rough idea about EIS study 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
- tr_bright_lo (Study 000251)
Study 000251: ACRONYM: tr_bright_lo 20"x144" raster using 2" slit Objective: ---------- To observe small scale QS brightenings (blinkers, explosive events, nanoflares, bright points etc.) Conditions Necessary to Run & Pointing: --------------------------------------- A patch of QS near to disk centre Study summary ------------------- Slit/slot: 2" slit No of pointing positions: 9 Total spatial width: 20" Pixels in solar-y: 144 Exposure time: 30 seconds Cadence: 5 minutes 57 seconds Data rate: 3.5 kbits/s Compression: DPCM WARNING: None
