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#

• Data analysis routines

• Fitting EIS lines with EIS_MOMENT

• A Wrapper to the EIS Objects (EIS_GETWINDATA)

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#

• EIS study search tool in Solarsoft

Hardware#

EIS pointing and alignment issues#

• How do I get the most accurate EIS pointing information?

• How big is EIS's field of view?

• EIS Post-Launch FOV

• Offset between CCDs in the y direction

• Offset between CCDs in the x direction

• EIS pointing stability

• Pointing Information in EIS fits files

• Inter-instrument offsets for Hinode

• EIS internal coalignment

• Grating tilt (spectrum rotation) and effect on line ratios

• Co-alignment of EIS to magnetograms

Slits & Slots#

• Slit “Focus”

• Grating focus

• The tilt of the EIS slit

• 2" EIS Slit

• Diagnostics with the slot

CCDs#

• Hot pixels

• Warm Pixels

• Removing cosmic rays

• Top and bottom of hot/warm pixels maps

• How do hot and warm pixels affect line fitting?

Spatial Resolution#

• Estimating spatial resolution using observed features

JPEG Compression and EIS Spectral Line Profiles#

• The Impact of JPEG Compression on EIS Spectral Data

Wavelength Scale#

• What's the "orbital variation of line position" about?

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
