SUMER Software
Using IDL :
a) quicklook
= 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 K. Bocchialini
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
