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:

 |
- 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
