3.2.1 How to Plot Light Curves of HXT Data

 

It is possible to get light curves of the four HXT channels on a single page by using the routine PLOTT_HDA.   A sample plot is shown in Figure 5. If the HXT index or roadmap has already been read in using YODAT or another routine, then you can use the command:
IDL> plott_hda, roadmap
  You can also get HXT light curve plots by specifying a date and time. When you use this calling option with PLOTT_HDA it will use the HXT data stored in the Yohkoh observing log files, which is lower time and count resolution than accessing the data file directly. In the first example shown below, the data between 22:00 and 24:00 for 15-Nov-91 are plotted. In the second example, it will plot 30 minutes of data starting at 2-Dec-91 4:30.
IDL> plott_hda, '15-nov-91 22:00', '15-nov-91 24:00'

IDL> plott_hda,'2-dec-91 4:30',30
