Addition of Data - EC1 HCO⁺ Spectra Movie

This movie shows 372 minutes of observations in Edge Cloud 1 (EC1) at the Onsala 20m telescope in May 2005. When the line intensity data is progressively added together, the signal to noise ratio improves (2t → √2), and the noise (rms) is reduced from around 2 K to 28 mK, and a clear 5σ detection of HCO⁺ at 138 mK is revealed in Edge Cloud 1.
