lcurve (2 Series)
Enter multiples files for each time series Multiple files for each time series can be entered using an ascii file containing the list of input filenames. This list has the following format: filenames of the individual lightcurve or event file are listed one per line and the group of files that belong to different time series are separated by three slashes. In this example lcurve is run with two time series, each with four files, so the input file list, filelist.txt, looks like the following: me_a63924.lc me_a63934.lc me_a63954.lc me_a63968.lc /// me_b63924.lc me_b63934.lc me_b63954.lc me_b63968.lc Running lcurve to create light curve and hardness ratio plots The example uses the file list created above. The output lightcurve is binned with 300 seconds and data are organized in an interval with 219 points. When run with 2 time series lcurve calculates the hardness ratio. The three 300 sec bin time series, the hardness ratio and the sum of both time series are assembled in one array and passed to "PLT >" for plotting. By default lcurve prepares a plot based on the input to: Three plotting styles available: Hardness [1] ; Intensity vs Time (or Phase) [2]; Ratio & Intensity vs time (or Phase)[3] Enter PLOT style number (default=1)[3] 1however since all the calculated data are available in "PLT >" , any other plot (e.g. hardness vs time) can be obtained by using within "PLT >" the commands to turn on-off arrays.

Setting the plot to 1 "PLT >" plots the hardness ratio vs. the sum of the light curves; setting the plot type to 2 (= number of time series) "PLT >" the light curves (intensity vs. time) on separate windows; setting the plot type to 3 "PLT >" plots the light curves for series 1 and 2 followed by the hardness ratio vs. time in separate windows. After the default plot is done, within "PLT >" is possible to plot any axis vs any other by using the command "color on" or "color off" and "xaxis N" or "yplot M".
Three plotting styles available:
Hardness [1] ; Intensity vs Time (or Phase) [2];
Ratio & Intensity vs time (or Phase)[3]
Enter PLOT style number (default=1)[3] 1
