Study 000596:

ACRONYM: TimeLag_quietARQS

A sit-and-stare study for quiescent active regions and quiet sun areas
designed to investigate properties of coronal heating using a systematic
analysis of EUV light curves known as the time-lag method.  Time-lag
diagnostics correlate relative maxima that occur in light curves of
emission lines formed at different temperatures to detect cooling
trends in the observed areas.

(10) 283.7-284.7:  Fe XV 284.163.

Pointing:
---------

The target should be a quiescent (non-flaring) active region either on
the disk or at the limb; if no active regions are available, quiet sun
area anywhere on the disk.

Instructions to planners:
-------------------------

1) Place the context study PRY_slot_context_v3 on the timeline first.
2) Then append the TimeLag_quietARQS study. Adjust the number of repeats
   to fill the available time slot, preferably with a minimum total
   duration of 3 or 4 hours.
3) Then append the context study PRY_slot_context_v3 to
   to complete the sequence.

Warning:
--------

None
