An efficient algorithm for identification of PIL on Solar Dynamic Observatory (SDO) Helioseismic and Magnetic Imager (HMI) magnetograms.
Detailed description will appear in the paper: Volobuev, D.M.
Polarity-Inversion Line Preceding X-class Flare, Solar Physics,
Initial data (65 megabyte .fits magnetograms) can be downloaded from http://hmi.stanford.edu/
- Model_test_PIL_Open.m script - calculates parameters of the example(simulated S-curve)
- SDO_PIL_Open.m script - identifies PIL on SDO magnetogram and calculates its parameters
- 5 functions are used within these scripts
