Observations and Data Reduction
===============================

The present study is based on the same data set obtained via Far-Ultraviolet Imaging Spectrograph (FIMS) as was used previously in the studies of @ryu06 [@ryu08] and @jo11. FIMS is a dual-channel FUV imaging spectrograph (S-band 900 [Å]{}-1150 [Å]{}, L-band 1350 [Å]{}-1750 [Å]{}) on board the Korean microsatellite STSAT-1, which was launched into a 700 km sun-synchronous orbit on September 27, 2003 and operated
