Anyone know a source for a mathematical analysis relating the slit-size/throughput for a spectrometer vs SNR?(adsbygoogle = window.adsbygoogle || []).push({});

I find that I always get better SNR (but not necessarily resolution) with a wider slit or higher throughput monochromator when doing emissions work.
