Access to UVCS/SOHO Data and Data Analysis Software

Data Policy

Distribution of UVCS/SOHO data is governed by the UVCS/SOHO Data Policy.

Access to Data

Data can be accessed from the SOHO Archive Main Catalog. If you are unable to obtain data from the SOHO Archive Main Catalog, please report the problem to Luis Sanchez (lsanchez@esa.nascom.nasa.gov), and please contact Raid Suleiman (rsuleiman@cfa.harvard.edu) to make arrangements to receive the data directly from SAO.

Data Analysis Software

The UVCS/SOHO Data Analysis Software (DAS) and calibration and help files are available from the SOHO Software Web Site.

The UVCS Analysis software, calibration and help files are also available here. None of the calibration files below are for versions of the DAS before version 40; please download DAS 40 and all calibration files together (first item below) if you have an older version. More information about new calibrations and features in DAS 40 is available at the online DAS 40 documentation, as well as documentation included with the DAS 40 download.

If you have an existing DAS 40 installation and wish to update your calibration or catalog files:

  1. download the appropriate tar.Z file(s) below
  2. extract the files via uncompress -c filename | tar xvf -
  3. copy files to appropriate the directory within your DAS installation:
    • DAS40/CAL/ for calibration and auxiliary xtalk files
    • DAS40/TABLES/ for UVCS catalog tables

---- Download the NEW DAS40 software with latest calibration and catalog files as a tar.Z file (Updated 5/1/2006)
---- Download latest calibration files (including latest auxiliary crosstalk files) as a tar.Z file (Updated 5/1/2006)
---- Download latest auxiliary crosstalk files alone as a tar.Z file (Updated 5/1/2006)
---- Download latest UVCS Catalog tables as a tar.Z file (Updated 5/1/2006)

Other Data Analysis codes

---- Download Curve-Fitting Software as a tar.Z file
---- Download IDL USR Library Supplement to the curve-fitting software as a tar.Z file
---- Download Coronal Ultraviolet Emission Synthesis codes as a tar.Z file
---- Download Pre-flight flat fields of the detectors (UCB or "Berkeley" flat fields

To extract tar.Z files use: uncompress -c filename | tar xvf  -
---- example: uncompress -c das32.tar.Z | tar xvf -

On-orbit flat field data [note that pre-launch UCB flat field is downloaded with calibration files (see above)]:

---- Download pre-September 1997 LYA flat field (hold down the SHIFT Key !)
---- Download pre-September 1997 OVI flat field (hold down the SHIFT Key !)

---- PAPER (PDF format): Flat field of UVCS detectors for early part of SOHO Mission

Please see the online Tutorials for information regarding running the codes.
For more information or questions, please contact Raid Suleiman .

Notes (as of 08 February 1998):

February 05, 1998: Added links to tutorials, line-profile fitting codes, and coronal modeling codes.

November 03, 1997: Catalog information are available from April 01, 1997 to August 25, 1997.

September 26, 1997: The DAS is compatible now with IDL 5.0.
