Name:
mpil.pro
Purpose:
Calculate Calculates some characteristics of strong-gradient, strong-field magnetic polarity inversion lines (MPILs) in active regions
Calling sequence:
output_mpil=mpil(c_img [, mpil_info=mpil_info] [, mpil_xy=mpil_xy] [, binxy=binxy] [, detail1=detail1] [, minsize1=minsize1] [, pbt_thresh1=pbt_thresh1] [, thresh1=thresh1] [, isth_cut1=isth_cut1], $
[ detail2=detail2] [, minsize2=minsize2] [, pbt_thresh2=pbt_thresh2] [, thresh2=thresh2] [, isth_cut2=isth_cut2] [, sep=sep] [, xy_pixel=xy_pixel])
Input parameters:
c_img - : Blos and Br images from SDO/HMI Space-weather HMI Active Region Patch (SHARP) cylindrical equal area (CEA) near-realtime (NRT) data
...
r or Blos SHARP cutout magnetogram, corrected for limb presence. Blos cutout should be deprojected.
Input Keywords:
binxy - number for xy spatial binning of the sharp magnetic field input data [in pixels] ; default=1 (i.e., no binning)
...
xy_pixel - xy distance from MPILs for calculating total unsigned magnetic flux around MPILs [in Mm]; default=2
...
Output
...
Keywords:
mpil_info - information on types of MPILs
mpil_xy - x and y coordinates of MPILs [pixels]
Output
...
:
output_mpil - 3 element 1D array related to the properties of MPILs
