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

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.

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

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

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

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

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.

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
