/* ** ** Swift/XRT hardness ratio for Mrk 501. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 58630.105651 0.000362 0.20616 0.04911 0.92800 0 2.15552 0.21160 1.85381 0.18201 0.44437 0.09646 0.38340 0.08321 58630.106372 0.000359 0.16128 0.03903 0.96774 0 2.39810 0.22189 2.06841 0.19132 0.38676 0.08648 0.33389 0.07466 58630.107405 0.000674 0.25418 0.04075 0.97854 0 1.98268 0.14651 1.71931 0.12704 0.50395 0.07170 0.43699 0.06217 58630.108400 0.000321 0.18150 0.04366 0.95495 0 2.51061 0.23622 2.16714 0.20386 0.45568 0.10088 0.39185 0.08675 58630.109083 0.000362 0.16607 0.04015 0.96000 0 2.31939 0.21315 2.01002 0.18472 0.38519 0.08613 0.33389 0.07466 58630.109751 0.000307 0.19346 0.04724 0.96226 0 2.35877 0.23152 2.03186 0.19944 0.45632 0.10204 0.39281 0.08784 58630.110391 0.000333 0.17571 0.04276 0.98261 0 2.39357 0.22403 2.06058 0.19282 0.42058 0.09448 0.36285 0.08152 58630.111085 0.000362 0.20622 0.05073 0.99200 0 1.80940 0.18545 1.56684 0.16059 0.37313 0.08344 0.32312 0.07225 58630.111826 0.000379 0.17863 0.04409 0.96947 0 2.01230 0.19486 1.74259 0.16874 0.35946 0.08161 0.31128 0.07067 58630.112581 0.000370 0.17046 0.04131 0.99219 0 2.13675 0.19977 1.85071 0.17302 0.36423 0.08144 0.31549 0.07054 58630.113461 0.000509 0.13314 0.03170 0.97159 0 2.03093 0.16627 1.75966 0.14406 0.27041 0.06047 0.23431 0.05239 58630.114410 0.000440 0.14246 0.03424 0.99342 0 2.20098 0.18789 1.90613 0.16272 0.31356 0.07044 0.27154 0.06100 58630.115738 0.000888 0.14610 0.02591 0.96743 0 1.95817 0.12365 1.69603 0.10710 0.28608 0.04742 0.24778 0.04107
