PR_EVN helps you find times for which Yohkoh data are available. An event is driven
by a change between QUIET and FLARE mode, or when there is a data gap of more
than 60 seconds. By typing:
IDL> pr_evn, '23-jun-92'
a list of the times that Yohkoh data are available and the number of datasets
available for each instrument is listed for 24 hours starting at 23-jun-92 00:00.
By typing:
IDL> pr_evn, '15-nov-91 20:00', '17-nov-91 15:00', /flare
all times that Yohkoh was in FLARE mode between those times are listed. By typing:
IDL> pr_evn, '1-jan-92', '9-jan-92', /flare, /counts, mindur=5, outfil='pr_evn.results'
the FLARE modes for 1992, and since the /COUNTS option was used, the maximum
counting rate for certain WBS, HXT, and BCS channels are printed instead of the
number of datasets available. It also prints the GOES classification when
it is available. The command shown above results in the following listing:
