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.

• The EIS study infomation such as line list, winodw size, exposure time etc. can be found on Hinode/EIS website (MSSL).

• There two useful webpages especially:

Studies Available for EIS

EIS Study Use Summary

• 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
