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!!

  • See FixDailyReductions for notes on fixing problems

• 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.

WSO Monthly Reductions

Always consult notes from the observer to identify problems/concerns. Follow up if data appear bad.

Mean field Reductions

In ~wso/src/reductions

• Run MF.monthly - reduction of meanfield data

  • Evaluate the individual meanfld observations
    • look for consistent values, duplicate entries, timing of observations, large errors, end of day, etc.
    • change the first character of bad measurements from from '+' to '-'; always have a reason

In /wso/scans/mf

• Make monthly MF table with mftable year=YYYY month=MM > WSO_MF.YYYYMM.txt

• Rename already created bartels.ps and bartels.gif plots to WSO_MF.YYYYMM.ps and WSO_MF.YYYYMM.gif

• Verify plots and table are good, then move WSO_MF.YYYYMM.gif, WSO_MF.YYYYMM.ps, & WSO_MF.YYYYMM.txt to /anonftp/SGD for transfer to SGD

Magnetogram Reductions

In ~wso/src/reductions/www.dailymags

• Run makewwwmags to make daily plots

  • evaluate new each magnetogram on /wso.stanford.edu/daily

  • set trouble bits as needed with settrouble

  • If necessary, partial lev3 magscans can be created with pokel3_runs for use in synoptic maps

In ~wso/src/reductions/www/SGD.monthly.mgmlists

• add best daily mgm to monthly file, list.yyymm in www/SGD.monthly.mgmlists

• run complete monthly files, list.yyyymm to make daily plots in /anonftp/SGD/yyyymm

Synoptic Chart Reductions

Photospheric field synoptic maps

In ~wso/src/reductions

• run Wextendsynop to extend synoptic time series

• run synopplots.ph {CR} to make good CR plots , evaluate, and move to /anonftp/SGD

Coronal Synoptic Chart

• run sph2.monthly

• run synopplots.ss {CR} , evaluate, and move to /anonftp/SGD

Web Page Reductions

Update the WSO web pages

• run ~wso/src/reductions/www/www.dorot {CR} for each altered rotation.

  • this updates all of the appropriate wso web pages with the latest info.

Publish data with SGD

ftp data to SGD transfer directory from /anonftp/SGD

• cd /anonftp/SGD

• ftp incoming.ngdc.noaa.gov
• use anonymous ftp and go to pub/incoming/wso
  • make the wso subdirectory if needed
• transfer three monthly MF files, .txt, .gif, .ps
• transfer new synoptic photospheric and coronal plots, both .gif and .ps
• lcd yyyymm
• transfer all of the daily magnetogram plots for the month, both .gif and .ps
