To reproduce our sample output

• Get the data file
• Get the downloadable idl code of the program and save it as sgt.pro
• To run the program type .run sgt at the idl prompt.
• When asked for the start and end time type 8.42 as the start time and 9.92 as the end time to get the output shown in the Sample Output. Remember start and end times are given in decimal hours.
• Type d or t depending on the analysis to be carried out on diff or time. Results in the output file are based on diff.
• If analysis is to be carried out in diff then give minimum and maximum diff. In our example we have chosen 0.6 and 4 as minimum and maximum diff.
• Next choose the number of data points to be used to calculate the moving average of the mean and standard deviation of log field. Examples are based on 20 data points.
• Choose bin size for calculation of distribution of normalised data. It is 0.2 in our example.
• Choose minimum number of data points in each bin. Satistical significance test will be carried out only with those bins which have at least this number of samples. In our example we have used 10.

  To run your data

• Get your data file
• Get our IDL code
• Modify data file specifications in IDL code (name, numbers of rows and columns, identification of relevant columns)
• Save the file with pro extension (e.g. filename.pro)
• Run by typing .run filename at the idl prompt
• Input necessary parameters (start and end times, minimum and maximum diff, d or t, number of points for moving average, bin size in X)
