Hinode/EIS Data Products and Archive Access
Jian Sun (MSSL)
EIS Basics:
1. work as Imaging Spectrometer to do either raster scanning or sit-and-stare observation
2. four slit/slot sections: 1”, 2” and 40”, 266”
3. core line: Ca XVII (192.8A), Fe XII (195.12A), HeII (256.32A) + multiple project lines
4. temperature coverage: log T = 4.7, 5.4, 6.0 - 7.3 K
5. spatial resolution: 1 arcsec pixels 2 arcsec solar resolution
6. line spectroscopy with ~ 25 km/s pixel sampling

Hinode/EIS Data Access: from Satellite to Users:
MSSL Hinode/EIS Data Archive (webpage: http://msslxr.mssl.ucl.ac.uk:8080/SolarB/)
Deliver EIS data to the end-user in a easy way See the data first before downloading Useful information is provided on website for Hinode/EIS Interactive help desk (EIS wiki)
Select * from eis_level0 as t1 where t1.DATE_OBS > '2007-03-03T00:00:00' and t1.DATE_OBS < '2007-04-03T00:00:00' and t1.SLIT_ID=‘40”’ and t1.TARGET = ‘Active Region’ order by t1.DATE_OBS
SQL query for complex search
Four catalogue tables in EIS DB
1. eis_level0
2. eis_level2
3. eis_thumbs
4. eis_studies
Select * From eis_level0 as t1 where t1.DATE_OBS > '2007-09-01T00:00:00' and t1.DATE_OBS < '2007-09-02T01:00:00'

There are over 230 EIS studies available for your observation!
but if there are special requirements:
1. Design your study with EIS software tools: eis_mk_raster, eis_mk_study, etc.
2. Submit your science proposal and study design to eis_obs@mssl.ucl.ac.uk
3. EIS operation4. Access the data from MSSL Hinode/EIS data archive
All information about EIS planning and studies are provided on MSSL Hinode/EIS website!
