About DAS 40

DAS 40 includes important calibration updates as well as a number of improvements and new features. It is strongly recommended that all users download this newest version

Calibration changes include a new time-dependent calibration scheme, which incorporates radiometric and pointing calibration changes. Radiometric calibration changes have been substantial for small apertures since the start of the mission.

Other additions include many interface updates and IDL compatibility updates.

For complete details about calibration changes and other DAS updates, see DAS 40 Updates.

Download the latest DAS


Download the NEW DAS40 software, including latest calibration and catalog files as a tar.Z file (Updated 3/19/2007)

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 (overwriting old files if necessary) to appropriate the directory within your DAS installation:
Download latest calibration files (including latest auxiliary crosstalk files) as a tar.Z file (Updated 3/19/2007)
Download latest auxiliary crosstalk files alone as a tar.Z file (Updated 3/19/2007)
Download latest UVCS Catalog tables as a tar.Z file (Updated 3/19/2007)

The UVCS/SOHO Data Analysis Software (DAS) and calibration and help files are also available from the SOHO Software Web Site, and are included in the SolarSoft package.

Notes:


DAS 40 is compatible with IDL 5.3 through the latest version tested (6.1.1).

Version 40 of the DAS has a calibration scheme that is incompatible with the previous calibration scheme. This difference leads to some important points:

SSW USERS: If you are running under SSW, you must run the DAS in its "DPS" directory just as if you were running it outside of SSW. The easiest way to do this is "cd $SSW_UVCS/DPS" from your unix prompt before entering "sswidl".'
