1. Made raster scans in [Fe X] 6374 Angstrom, [Fe XIV] 5303 Angstrom,
[Fe XIII] 10747 Angstrom, and [Fe XI] 7892 Angstrom coronal emission lines
choosing two lines simultaneously out of these four with exposure times of
10-60 seconds covering coronal regions of about 200 x 500 arcsec to study
the variations in line parameters as a function solar cycle phase.
