Reduce t1 noise

Reduce t1 noise (Not available in Mnova Lite):

t1 noise is a particularly troublesome type of artifact which appears as streams of signals or ridges. The ridges (which are associated with strong signals in a contour plot), run parallel to the f1 axis and are found at their chemical shifts along the f2 axis. They can seriously interfere with the observation of real cross peaks from the signals.

The t1 command allows the user to clean up the spectrum along the f1 dimension by a factor proportional to the r.m.s. noise of that trace. It takes advantage of the fact that t1 noise is normally associated with the intense peaks which can be reduced without a significant loss of information.

The algorithm for t1-noise reduction has been designed to work with HSQC-like spectra.

This command is available by following the menu 'Processing/More Processing/Reduce t1 noise'.
