This is the adaptive sounding sampling task, which is used by the
normal_scan_nodata RCP to count the amount of scatter received.
The task receives fit data from echo_data and uses the sampling routines in
the Radops2000 library to calculate the number of beam/range points which
have more than a specified value of a selected parameter. The minimum
distance at which scatter should be counted can also be specified.
no_data is used by sending a QNX message requesting either that the scatter
count be returned or that the count be reset.
The task is compiled by typing 'make' in the no_data directory. This compiles
and links two versions of the file, the normal version and a debugging version
which displays useful information on the console.
Usage information is available from the QNX 'use' command.
