epspatialcti (epspatialcti-0.4) [xmmsas_20211130_0941-20.0.0]


Algorithm

Open the input event file
Read the observing mode from the input event file
Read from the EPN_CTI CCF coefficients and template values

Loop over each event

   set coefficients(a,b,c) from the event CCD, RAWX, RAWY values
   set template value from the event CCD, RAWX, RAWY values

   h = log10(event_pi) - 3.0;
   f = a + (b + c * h) * h;

   event_pi = event_pi - template_value * f

end of loop

Add the keyword SPATCTIC = 'yes' into the EVENTS header
