Data: The data file WG1.dat contains several sets of data delineated by *******
filename ********** where filename refers to the following files:
psf.dat - the point-spread function data. Each line consists of 12 numbers (the
measurements on 12 detectors) followed by the coordinates of the point source (azimuth and
elevation). Measurements are made at one degree intervals over +- 40 degrees. Thus, there
are 6568 (81*81) lines. The data in the range +-30 degrees were used in the study.
noise.dat - measurements made with the transmitter turned off. Again, there are 12 numbers
on each line followed by two angular coordinates, but these can be ignored. There are
78732 lines. line25.dat - line scan at an estimated signal-to-noise ratio of 37dB
line12.dat - line scan at an estimated signal-to-noise ratio of 31dB line6.dat - line scan
at an estimated signal-to-noise ratio of 27dB line3.dat - line scan at an estimated
signal-to-noise ratio of 22dB line2.dat - line scan at an estimated signal-to-noise ratio
of 19dB
Each of the above files contains a scan across the point source at different
signal-to-noise ratios. Each scan is in steps of 3 degrees over +-39 degrees at 0 degree
elevation (27 measurement positions; again, only +-30 degrees was used in the study). At
each position, 600 measurements are taken, giving 16200 (600*27) lines in each file.
