Two output platforms are created: an \"analysis\" platform with optical depths and solar constants, as well as flags for whether the given Langley plot was rejected or not; and a \"plot\" platform with the time series information necessary to display a Langley plot (i.e. lnIs vs. airmasses). One Langley plot is performed for each half-day (i.e. between airmasses [2,6]). The analysis platform therefore contains two data points per day; the time stamps are for the median time sample within each Langley plot period. The plotting platform files hold only the information for one plot, so two plotting files are created per day.
