TSIS-1 SIM Recalibration of the SORCE-SIM Absolute Irradiance Scale

This TSIS-Adjusted Value (TAV) SORCE-SIM irradiance calibration provides a TSIS1-SIM/SORCE-SIM ratio on the SORCE-SIM wavelength scale. This scale varies in spectral resolution from 1-34 nm over the spectral range. Irradiances are reported at a mean solar distance of 1 AU and zero relative line-of-sight velocity with respect to the Sun. The SORCE TSIS-1 Irradiance Calibration Ratio (STICR) is tabulated is the attached datasets, containingn the wavelength, number of spectra combined at this wavelength, SORCE mean spectral irradiance, its 1-sigma standard deviation of the mean (STD), standard error of the mean (SEM), uncertainty (UNC), data release version, TSIS-1 mean spectral irradiance, its 1-sigma STD, SEM, UNC, data release version, the STICR (TSIS/SORCE), its 1-sigma STD, SEM, UNC, co-variance squared (CV2), and auto-correlation (PHI). The TAV auto-correlation (PHI) was constructed using 15-day bins evenly spaced over the overlap region.
