FOS Advisory: Some FOS STARVIEW reports may be misleading

The STARVIEW screen which reports a comparison of the `Used' vs latest `Recommended' Calibrations available for any given FOS dataset is misleading in certain cases. When reporting on a dataset which was archived before the Average Inverse Sensitivity (AIS) flux calibration method was available this tool correctly reports that none of the associated calibration files were `used' and also correctly lists the files needed to perform this calibration. However, the STARVIEW screen incorrectly qualifies the `Level of Change' of these calibrations as `N/A'. The AIS corrections are ALWAYS RECOMMENDED. This notice applies as well to data archived before implementation of the default Scattered Light Correction (.cy9 reference file).
