It displays graphs of the river flow data (which is distributed with
GRASP) and spectrum before and after automatic removal of the two
significant spectral lines (whose frequencies are 1/year and 2/year).
These graphs are also shown here. Before running this program, be sure to set the envionment
variable giving the path to the river data, for example:
setenv GRASP_PARAMETERS /usr/local/GRASP/parameters
The text output of the program is as follows:
Total number of lines removed: 2 Removed line of amplitude -0.291175 + i 0.312209 at freq 1.005848 cycles/year (F-test value 48.455242) Removed line of amplitude 0.023220 + i 0.098357 at freq 2.000000 cycles/year (F-test value 15.224311)
