Comments

• omthlcplot is designed to produce plots of light curves measured by the OM. However, any file containing a RATES header extension with 1-99 columns can be plotted with this task.
• If the output file is postscript, the optimum presentation can be achieved using A4 portrait. However, no more than 15 plots per page are recommended as it then becomes difficult to view the individual plots.
• Error rates are rebinned following a quadratic scheme (Central limit theorem).
• Time intervals all have the same length, the first one is $[$TSTART , TSTART + Binsize*TIMEDEL$]$ where TIMEDEL is the bin width read from the file [1].
• We note in [1] that the keyword TIMEDEL is specified in MJD. We have assumed it to be given in seconds.
• Time on the X-axis is given, beginning from T-TSTART, in seconds.
• The output devices are those of the PGPLOT library. The device list is governed by the drivers access to PGPLOT.
