/* ** ** 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 58907.388176 0.000683 0.27069 0.06845 1.00000 1 2.56463 0.30274 0.62975 0.07434 0.69422 0.15524 0.17021 0.03806 58907.389454 0.000596 0.28192 0.07187 1.00000 1 2.79702 0.34230 0.69150 0.08463 0.78855 0.17633 0.19512 0.04363 58907.390689 0.000639 0.26139 0.06587 1.00000 1 2.78359 0.32344 0.69364 0.08059 0.72760 0.16270 0.18182 0.04066 58907.392098 0.000770 0.23513 0.05839 0.94340 1 2.73612 0.29549 0.67782 0.07319 0.64334 0.14386 0.16000 0.03578 58907.393710 0.000842 0.25368 0.06426 0.98276 1 2.23764 0.25879 0.54852 0.06344 0.56765 0.12793 0.13934 0.03140 58907.395221 0.000668 0.30316 0.07811 0.97826 1 2.37069 0.30338 0.58635 0.07503 0.71870 0.16071 0.17778 0.03975 58907.396891 0.001002 0.24654 0.05342 0.98776 1 2.65530 0.25971 0.65134 0.06371 0.65463 0.12657 0.16094 0.03110
