create_json_for_web

This code creates a JSON file (sigmoid_webpage/json.txt), which the sigmoid webpage uses to put information in each row, and is the last code to run in the Sigmoid Catalog suite. Primarily, the information comes from a .csv file, which was created by Patty Bolan in July of 2018 and updated by Jakub Prchlik in December 2018 (SigmiodCatalogAll_filament.csv). This .csv file is commonly used as input throughout all programs in this code suite. If you are running the code with default parameters the call is simply:

sswidl>create_json_for_web,’SigmoidCatalogAll_filaments.csv’

As stated previously, running this code creates the JSON file sigmoid_webpage/json.txt. The heavy lifting the code stems from the need to create links for all movies and plots in the JSON file. By default it searchs in the “combined_movies/” directory (can be changed by setting the out_arch keyword) for the directory corresponding to the sigmoid ID for a particular sigmoid. Once it has the sigmoid ID, it links the disk passage HMI movie in the hmi_movie sub-directory, the sigmoid long AIA/XRT movie in the aia_movie sub-directory, and all flare movies in the flr_movie sub-directory using relative paths. From the flare movies, the code counts the number of X, M, C, and B class flares. Some sigmoids (below a sigmoid ID of 70) are missing flares due to a prolonged data outage at JSOC. The flare movies were created by a different code, so see make_aia_flare_movies for more detailed information on the flare association.

All information printed into that file in the code starts with a printf,33 followed by some text.

However, create_json_for_web may take a few additional keyword arguments, which .

Technical Notes

If for some reason create_json_for_web errors before the free_lun command, then you will need to run the following command before re-running create_json_for_web:

sswidl>free_lun,33

This command with free the file unit used in writing json.txt.

NAME:
