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

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!
