The interactive smeared gas transmittance calculator and plot is available for download. This is a tool we used to plot chart in the “Smeared Gas Transmittance Revisited” paper. It lets you play with some basic parameters of a gas cloud and a detector and see the transmittance. Currently only 2D/1D gas cloud is supported.
This is a Wolfram Mathematica interactive notebook. You may use the free Wolfram notebook player if you don’t have the Wolfram Mathematica app.
