SUMER User's Guide for UNIX (by D. M. Zarro, GSFC)

Other SUMER Data Analysis Software at GSFC

Here is a listing of some of the IDL software which has been contributed for use by people analyzing SUMER data. All programs are provisional. If you have trouble with any of the programs, try contacting their authors. Use all programs with care. Check your results! Most programs call other programs in the software tree. These include some programs in the IDL Astronomy User's library . These are also part of the software packages for some other IDL instruments, including CDS.

The programs can be found in various subdirectories of the sumer contributed software which can be accessed from either
http://sohowww.nascom.nasa.gov/solarsoft/soho/sumer
or via anonymous ftp from sohoftp.nascom.nasa.gov in the directory /solarsoft/soho/sumer.

There is also a mailing list for SUMER software issues. The email address is sumer-soft@sohomail.nascom.nasa.gov
To subscribe to this list send a mail message to
majordomo@sohomail.nascom.nasa.gov
with an empty "Subject" line and (for example) "subscribe sumer-soft" as the content of the message. If you subscribe and after two or three days you do not receive any message, try to subscribe again with "subscribe sumer-soft [your e-mail address here]".

Harry Warren has designed a program to read SUMER data into structures as is done with CDS and Yohkoh data. A number of the programs listed below are designed to work with those structures. More information can be found about these structures here. We would be happy for others to write software using these conventions.

List of some available routines

SUMER FITS file reading

ft_sumread_fits - reads sumer fits files into data cubes
rd_sumer - Part of the sumer data structure package. Reads the data into index and data structure inspired by the ones used in Yohkoh data analysis.

Flatfield Application

At present all our flat field routines simply apply the regular flat fields taken on board.

sum_ffield - applies flat field to data cube
flatfield - structure based flat field program

Destretching - correction of warping of the detector

destretch - corrects warping for a single frame of data. You will also need some accompanying data files. At the moment some file names in the code need to be changed to run the program on a new machine.
call_destretch - a structure based program which calls destretch and analyzes up to a FITS fiels worth of data at a time.

Compression & line fitting

sf_gaussB - performs the Gaussian B4 compression (scheme #12, which can be applied to SUMER data on board) on a data cube.
sum_gaussB - applies sf_gaussb to a sumer data structure

Data visualization and general analysis

xraster - widget based tool for analyzing sumer data. Includes programs to do flat fielding, gaussian fitting, and other things

Reference Spectra

smk_atlas - a structure based routine to make spectral atlases out of reference spectra data

Sumer Catalog

There is a listing of sumer observations here.

xselect_sumer - a program to find sumer data based on information in the fits headers. Calls log files from sumer

There is a SUMER software page in Oslo now.

You might also take a look at the SUMER Data Cookbook, to make all data corrections with IDL restore files
