                            throws java.lang.Exception

Makes a spectrum fingerprint

Parameters:

signals - The signals

fromSpec - true=shifts come from datbase; false=they do not.

Returns:

The fingerprint

Throws:

java.lang.Exception - Database problems

                                       throws java.lang.Exception

Determines if there is a signal in a certain range

Parameters:

v - The signals

base - Lower limit

end - Upper limit

fromSpec - true=shifts come from datbase; false=they do not.

Returns:

false=no signal in that range, true=one or more signals in that range
