SNR-controlled Experiments

Acquisitions of long 1D spectra with user defined number of scans, such as C13CPD, is controlled by an au program, which checks the signal-to-noise ratio (SNR) every ~30 seconds. When the high enough value is reached (200 for C13CPD), the program automatically terminates the acquisition and switches to the next experiment. Note that the solvent signals are excluded from SNR estimates.
