Documentation for WSO Data Reductions

One-time set up

• Make sure your paths are set up correctly and all directories are mounted
  • Top level reduction routines are mostly in ~wso/src/reductions
  • Raw data and reductions scripts are in /data/scans subdirectories
  • Final data appear in /wso/scans subdirectories
• Make sure you have read and write access to the appropriate files and directories
• Make sure your umask is set for group read/write permissions
• Make sure your .cshrc is set up properly for "DOREDUCTION"
• STOP if you have any questions or anything does not work properly

Daily Reductions

• Verify that you are using a color printer
• Run 'checkwso' to see which days need to be reduced,
  • This provides a list of files that have transferred from the observatory. The first part of each file name is the two-digit month and two-digit day of month.
• Execute "Dotel MON DAY" where
  • MON is the 3-letter Month (e.g. Jul for July, first letter capitalized)
  • DAY is the Pacific Time Day (number 1-31, no leading zero)
• Look carefully at the output to see that
  • the meanfields and magscans have been listed and the reductions have been successful
  • the magscan plots look good
  • You can find the reduction scripts in /data/scans/reduction.scripts
  • You can remake plots with 'mplots' in ~wso/scripts

  IF ANYTHING DOES NOT LOOK RIGHT STOP AND ASK FOR HELP!!! DO NOT PROCEED WITH MORE REDUCTIONS!!

• If there are magnetograms
  1. Examine plots and set trouble bits as required with 'settrouble'. Alert observer if it looks like there's a systematic error
  2. Run Dolev3 if a good magnetogram exists. This updates daily WSO web pages.
