PLOTY plots light curves from all the Yohkoh
instruments on the same plot with the same time axis. If you have the
observing log on-line and wish to use it to make the plots, you can
specify the plot times. It is recommended to plot no more than
approximately 24 hours of data at a time. An example is:
IDL> ploty, '8-may-92 15:00', '8-may-92 18:40'
If you have identified an instrument file for which you want to see the light
curve for all the other instruments, you can use the following command
(it assumes that the other instrument data files exist on the same
directory as the input file):
IDL> ploty, infil='/yd5/flares/spr911115.2141'
You can read the observing log data, and the use PLOTY with a command
like:
IDL> rd_obs, '8-may-92', '8-may-92 12:00', bcs, sxtf, sxtp, w_h
IDL> ploty, bcs, w_h, sxtp, w_h
