EIS Data Processing and Analysis
#

Getting started#

• EIS data analysis tutorial (Paris meeting, Nov 2007)

• EIS Tips (en) @ National Astronomical Observatory of Japan (NAOJ)

• EIS Tutorials @ Naval Research Laboratory (NRL)

• EIS Data Analysis Guide @ Mullard Space Science Laboratory (MSSL)

• EIS Spectroscopy analysis tutorial (on SOLARIE-SODAS, Glasgow June 2009)

Software#

An EIS FITS file is read into an IDL object with:

IDL> data=obj_new('eis_data',filename)

where 'filename' is the name of the level-1 file (a level-0 file can be read in the same way). Information can be extracted from the object via a large number of object methods.

• Data analysis routines

• Fitting EIS lines with EIS_MOMENT

• A Wrapper to the EIS Objects (EIS_GETWINDATA)

• Using the EIS Subversion Repository

EIS_PREP#

• How do I call EIS_PREP?

• What does EIS_PREP do?

• Evaluation of errors in EIS_PREP

Gaussian fitting#

The document below details software available in the EIS Solarsoft tree for fitting Gaussians to EIS data.

Gaussian fitting for the Hinode/EIS mission

Examples for using the routine eis_auto_fit to automatically fit Gaussians across a raster are given in the document below.

Gaussian fitting examples using eis_auto_fit

FITS file issues#

• Big EIS FITS files

• EIS exposure times; the GETEXP() method

• Missing data/missing files

Search EIS studies#

• Searching for EIS Studies on the Web

• EIS study search tool in Solarsoft

Miscellaneous#

• EIS_CAT and the EIS Science Data Catalog

• How can I see where EIS was observing? Try the EIS Mapper @ GMU

• The Complete List of EIS Studies

• Suguru Kamio has uploaded an EIS spectral atlas, using data from Charlie Brown's line list paper. Best suited to A0 paper, but readable as a PDF.
  Other resource of EIS Spectral Atlases can be found here or directly access a few PS file: Active region;   Quiet Sun;   Flare
