EIS Planning & Operations


If you've come here, you've probably either clicked on the link in the Hinode/EIS Wiki sidebar and are wondering what this page is about; or you are looking for specific information.

This page is a sort of directory of various articles and discussions on planning observations with EIS. Some operational details are introduced in these pages by way of explanation. For example, if you are interested in finding out how to tailor your observations to be best suited for the way EIS works, check out our new page at SbandObservingInfo.

Or if you'd like to find an existing programme which suits the kind of observations you'd like to run, then take a look at SearchingForStudies. There's much more information besides, all below!

How to get your observations run#

For examples of what EIS is running these days, and who to talk to about proposing observations if you have questions, go over to PlanningObservations. And to find out what you should submit with your observation request, check out the guidelines in Newstudies.

S-Band Era Observing - new#

Since Hinode made the switch to the S-Band antenna, there are a number of considerations to bear in mind. These are described on our Wiki page at SbandObservingInfo.

And for an idea of studies designed to optimised for this antenna, see some examples at Study4LowDataVolume.

Searching for and Decoding the contents of an EIS Study#

To look up an EIS observation, or Study, and find out how it's defined (using SolarSoft) you can use EisXstudy

Hinode eclipse season#

To find out what the annual ''Eclipse Season'' means for EIS, you can take a look at the original information posted at EclipseEffects last year, or the more up-to-date information in the Eclipse Season section of the new S-Band Observing Info page.

Requesting XRT support#

To request XRT support for your EIS observations, particularly if you do not intend to go through the HOP system, see the Wiki page at XRTSupport.

Some suggested studies#

As a place to start if you have no idea what to use with EIS, Peter Young has started a discussion page at RecommendedStudies.

Searching for studies#

There is already a large number of studies out there, already available to use. To help you find out if an existing programme would meet your requirements, Harry Warren and Ignacio Ugarte have written eis_search_rasters to help you find the right raster. Take a look at SearchingForStudies to find out how this powerful SolarSoft search tool works.

EIS Data Compression Factors#

Jian Sun has done extensive work on the effective Data Compression (DC) factors associated with the various on-board compression algorithms on Hinode. See CompressionFactorStudy for more on this. And go to NewNumberForEISDC to see the results of the variation of compression factor with target.
