IDL code for reading binary data:
    OPENR, u, binfile, /COMP, /GET_LUN
    head = FLTARR(6) ;[xsize,ysize,radius,hh,mm,ss]
    READU, u, head
    data = INTARR(FIX(head[0]),FIX(head[1]))
    READU, u, data
    FREE_LUN, u
    
  • each filament has the value of Fil_ID
  • all values are in pixel
to get the area of a filament:
  c = WHERE(data EQ Fil_ID, area)
  f = '(2(A,I6))'
  PRINT, FORM=f, "Area of Fil_ID", Fil_ID," =", area 
be careful: y-origin is upper left! you can transpose the data:
  data = ROTATE(data,7)
  Solar_y = 2048-Solar_y
