Algorithm

   Subroutine elcplot

     Recover parameters (File names, Device type, Binning factor, Output file, x-axis units)
        
     Read source time series FITS file : 
        Get dataset and table.
        Check important keyword consistency (notably TSTART and TIMEDEL).
        Call a warning or error if necessary.

     Recover all light curves included in table 
     Net source rates and errors & background rates and errors are recorded in arrays
        of dimension Nlightcurve * Nbins.

     Open plot : create view surface in specified device format (check its validity).

     if (usegtiset)  then 

     Recover GTIs 

     end if

     if (useflareset) then 

     Recover Flare light curve  and rebin according to the lightcurve binning pattern
     end if

        Delete gaps in data (when the IEEE NaN constant is found).

        Increase binsize if necessary to limit the number of points to 512.

        Rebin rate and error columns by binsize

        Create a labelled plot page separated into two panels in which time is graduated
        on X-axis (see Comments), and count rates on Y-axis (in counts/sec).

        Draw net source and background time series and GTIs on different panels.
               
     Release memory.

     Close plot.
