describing the in-flight radiometric calibration of the
Hinode EIS instrument

see doi: 10.48550/arXiv.2308.06609
 


The IDL save files contain a structure RETURN_STR with the results of the
fits of the single spectra, merged.

The main array is return_str.total_counts  which contains the
total counts in the lines for all the dates, in units of
DN/s/1arc sec

The array return_str.list_lambda has the expected wavelengths of the lines.

The arrays in data_active_sfit_2023.save
return_str.eis_sw_ar_spectra and return_str.eis_lw_ar_spectra
contain the active region averaged spectra. 

The arrays in data_quiet_sfit_2023.save
return_str.eis_sw_qs_spectra and return_str.eis_lw_qs_spectra
contain the quiet Sun  averaged spectra. 

The wavelengths can be obtained with
eis_pixel_to_wavelength(indgen(2048),1,2)
and
eis_pixel_to_wavelength(indgen(2048),2,2)
for the 2 arcsecond slit. 

Note that the spectra have not been wavelength calibrated. 


They are the result of the  processing of  a large number of EIS data
for the in-flight calibration from 2007 to 2022.



The routine used to process Hinode EIS full spectral raster atlases
is process_atlas.pro

The routine interpol_eis_ea.pro is to be used together with
the save file fit_eis_ea_2023-05-04_smooth.sav  to obtain the
time and wavelength-dependent effective area.
