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.



Studies Available for EIS

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 directly choose those suitable studies from the list rather than to design your own studies (unless been instructed to do so by EIS team).

EIS Study Use Summary




Examples of EIS studies under the low data-volume restriction:

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
