SUMER DATA REDUCTION AND ANALYSIS
1- Useful SUMER softwares:
Using IDL :
a) quicklook (ask K. Bocchialini or P.
Lemaire for a demo)
= quick look : To run this routine, just type quicklook
and select your data (fits-files) in
/home/yourlogin/yourpath
* If your files are not available, ask P. Lemaire
or I. Scholl
b) In the SOHO software environment, one magic routine will help you
to
correct your SUMER data from instrumental effects:
Just load ssw
sumer cds
and then
IDL> .r sum_read_corr_fits.pro (for
FITS files )
or IDL> .r
sum_read_corr_fts.pro (for FTS files in the official archive)
answer YES to the question HELP ? the header will appear as follows:
;Purpose:
; Read fits files (all the BTE)
or fts files
; Fill the gaps due to TM
; Apply the flatfield correction
if not done on board
; Apply the deadtime correction
(optional)
; Apply the pixel linearity correction
; Apply distortion correction
; Calibrate the data (optional)
; North-South Exchange to fit with
the real position on the Sun
;Calls:
; sum_FField(data,slit,ref_pix,FFfile)
; deadtime_corr,detector,input,output
; local_gain_corr,detector,data(k,l,m),new_data(k,l,m)
; radiometry(slit,wavelength,order,rate,/keywords)
; destr_bilin_multi(data,slit,ref_pix,detector,/Quiet)
;Use:
; IDL>.r sum_read_corr_fits.pro
;Output:
; Corrected data of each column,
for all the BTEs, in a
;
sum_yymmdd_hhmmss.sav
; file, where yy is the year, mm
the month and dd the day,
; hh the hours, etc....
c) with IDL opened through
"ssw cds sumer any_other_instrument_imcluding_trace"
do IDL> xdoc
and a list of useful routines will be displayed
