Making MDI CR Synoptic Charts

DESCRIPTION:

The magnetic and intensity Carrington Rotation synoptic charts are generated as soon as the definitive MDI data are processed for the period. They require 3 (4?) days of data after the official end of the CR.

INSTRUCTIONS:

To make the magnetic field charts:

  1. On your own machine (for speed), cd /synoptic/new_scripts/synop_qual.

  2. Run new_cr [CR] for the new Carrington Rotation.
    • The magnetograms for the entire CR (plus a few days after) will pop up in DS9 for you to look at.

    • To set the Cosmic Ray bits edit the file CR####.####-#### where the numbers are the CR, and the first and the last day. Indicate in the file the day and image numbers for which the bit must be set. When finished, run the file and save it in the directory CR.BitsSet.Lists NoteOnCosmicRays

    • If any other trouble bits need to be set, run 'udpate' in a sonar window. It will prompt you for the day and image numbers, and the quality bit(s) you want to set. Quality bit definitions are at http://soi.stanford.edu/production/QUALITY/.

  3. Once quality bits are set, run 'make_magsynop.pl [CR] [FIRST] [LAST] on n02 in the directory /synoptic/new_scripts

    • Here CR is the Carrington Rotation and FIRST and LAST are the beginning and end times of the CR. There is an alias called 'carrot' (run on sonar) that will get those times for you:

      • alias carrot "echo \!* > /tmp/cr;echo \!*;~kehcheng/work/synop/carrot < /tmp/cr"

        • sonar.Stanford.EDU: carrot 2067
          • 2067
          • T_FIRST = 2008.02.21_17:34:00_TAI 982690440.315253 5529.73
          • T_ROT = 2008.03.06_09:44:30_TAI 983871870.041679 5543.41
          • T_LAST = 2008.03.20_01:40:33_TAI 985052432.670730 5557.07
          • T_EARTH = 2008.03.06_09:31:46_TAI 983871105.862488
    • So to make the synoptic charts for CR 2067, on n02 run make_magsynop.pl 2067 5529.73 5557.07.
    • make_magsynop.pl puts the new files in /synoptic/carrot/M/[CR]
      • You can ignore the error messages about not being able to read the overview.fits files.
      • Missing magnetograms also generate a complaint
      This takes roughly 15 minutes to run.
  4. Make the gif images for the fits files that were created by make_magsynop.pl.
    • Run /ssw/gen/setup/ssw_idl on your machine.

      • IDL> .run /synoptic/new_scripts/plot_synop

    • For each of the 0, 30 E/W and 60 E/W fits files, and for each l and r, run plot_synop:

      • IDL> plot_synop, in='/synoptic/carrot/M/2066/synop_Ml_30W.2066.fits', /gif, /next, /carrot IDL> exit

  5. Check the images to make sure they look OK. You may need to set additional trouble bits if it looks like a bad image was used, and rerun make_magsynop.pl and remake the gif images. You can check the files online at
  6. Update /synoptic/carrot/latest to reflect the latest CR that's available when you have updated the charts.

To make the intensity charts

For a CR that had no events that would affect the intensity (ie, focus changes, tuning changes, spacecraft rolls or proton storms):

  1. On sonar, cd /synoptic/new_scripts/Ic_synop.
  2. Run get_data[CR] for the new Carrington Rotation. This will retrieve the lev1.8 files you need (which may take awhile) and make a mapfile for you to run.
  3. Run the mapfile (pe -v -A map=map.2067, for example). The mapfile does the following:
    1. makes lev1.8 data
    2. removes limb darkening
    3. makes a median filter using all of the Ic images without limb darkening for the CR
    4. makes lev2 data by applying the filter to the images without limb darkening
    5. remaps the corrected images
    6. creates the synoptic charts
  4. Make the gif images for the fits files.
    • Run /ssw/gen/setup/ssw_idl on your machine.

      • IDL> .run /synoptic/new_scripts/plot_Ic_synop

    • Run plot_Ic_synop for both fits files:

      • IDL> plot_Ic_synop, in='/synoptic/carrot/Ic/2066/synop_Ic_N=3.2066.fits', /gif, /next, /carrot

      • IDL> plot_Ic_synop, in='/synoptic/carrot/Ic/2066/synop_Ic_N=5.2066.fits', /gif, /next, /carrot

  5. Check the images to make sure they look OK. You may need to set trouble bits if it looks like a bad image was used. You can check the files online at
  6. Once the synoptic charts are done, make the lev2 GIF images on your machine.

To make the intensity charts for a CR that HAD events that would affect the intensity (ie, focus changes, tuning changes, spacecraft rolls or proton storms):

The median filter requires ~30 days of data that have no intensity changes due to events listed above. So for example, if there was a proton storm in the middle of the CR with an obvious change in intensity in the images, you would need 2 median filters - one for before the proton storm, and one for after the proton storm - and each filter would require 30 days of data. Note that each of those 30-day chunks also needs to have no events. This isn't always possible to do because of other events...a roll 5 days after the storm, for instance. If you can't get the 30-day chunks of data to make separate median filters, just process the data as if there were no events.
