%%(text-align:justify;)
We have run 40 " slot time-series data. Once we run the eis_prep with /noabs
keyword then we get the Intensity in 'DN' units. While, when we run the
same with absolute calibaration (without /noabs keyword), we get the intensity in absolute
cgs unit.However, this is surprising that when we are plotting intensities
with time, we are getting the different patterns of variations in the above mentioned
two cases. This is affecting our further analysis and also confuses which one we have
to choose. Either DNs one or absolute one ?? !!!!
Why they are giving different pattern?. There should only be the
difference in magnitude. why the pattern is also varying. Which one we have to choose for our further analysis ?
Is it here any problem with absolute calibaration of EIS ?
Please suggest !%%

!!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|EISmethods].

*Suguru Kamio has uploaded an [EIS spectral atlas|eis_atlas.pdf], 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|http://solar.bnsc.rl.ac.uk/ralsolphys/eis_ral.html] or directly access a few PS file: [Active region|http://solar.bnsc.rl.ac.uk/%7Eyoung/solarb_eis/atlas/eis_spec2.ps];   [Quiet Sun|http://solar.bnsc.rl.ac.uk/%7Eyoung/solarb_eis/atlas/eis_qs_spectrum.ps];   [Flare|http://solar.bnsc.rl.ac.uk/%7Eyoung/solarb_eis/atlas/flare_spec.ps]
