SXT DATA SELECTION

 
All flare images selected from the year 2000 SXT data have a peak with well localised emission. 
In addition they satisfy the following properties: 

1) The temperature of CCD during the image exposure was lower than -20 C, 
2) The image is taken outside the South Atlantic Anomaly SAA passages,
3) The image possess only a single pixel with maximum value (i.e. global maximum was present),
4) The pixel with maximum value is situated at least seven pixels away from the 
     image boundaries,
5) The maximum value is above 1000 DN,
6) The image is not saturated (i.e. maximum value below 3313 DN),
7) The maximum dark current level in the image is below 50 DN 
      (50 DN is an average dark current in reference frames for the year 2000)

8) The Fourier transform of the image is broad and possess more uniform distribution of signal value. 
 

Location of the compact sources selected in the year 2000 for BID deconvolution purposes is shown in the figure to the right.
