SHOW_OBS3 plots a time line summary of the SXT images that are in
the index or roadmap. In addition to plotting a tick for each image
available, it shows the DP mode, DP rate, where the S/C days
are, and where SAA passages occur. Some sample calls to SHOW_OBS3 are:
IDL> show_obs3, roadmap
IDL> show_obs3, index
It is possible to select images using SHOW_OBS3 by clicking on
diagonally opposite corners of a box surrounding the images you wish
to select. The calling sequence for that is:
IDL> show_obs3, roadmap, sel, ss
where sel is a returned logical array the same length as roadmap, and is set
true for all dsets selected, and ss is the returned subscripts of the selected
datasets. A few examples on how to use the sel variable are:
IDL> ss = where(sel)
IDL> ss = where(sel and (gt_dp_mode(roadmap) eq 9))
