Sherlock Quantification Sherlock Quantification • The Sherlock imaging spectrometer quantifies the concentration of the

gas as well as mass flow rate using a standard Beers Law technique as conventional absorption spectroscopy has done for years

Shown above is an Ethane leak where the gas is colored red with the higher concentration shown in the brighter red. A GUI indicates the concentration of any pixel within the gas cloud as shown on the right
