HZ43 (obsid 59) spectrum, with varying filtering levels. Red curve shows the problem with bit 21 filtering. All HRC-S data processed prior to July 2, 2001 are affected. (Figure by D. Pease.)
Lower panel: Spectra normalized to no-filtering spectrum, showing combined effect of PI and Status-Bit filtering including bit 21. Status-Bit #21 removes an extra 5% of valid x-ray events at all wavelengths, with periodic dips that remove roughly 20-40%. (Figures by D. Pease.)
Additional plots
confirm the effect of status bit 21 at
shorter wavelengths, on the central HRC-S segment.
