/* ** ** 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 57681.337459 0.000385 0.18965 0.04070 0.98496 0 3.36239 0.29155 2.09216 0.18132 0.63768 0.12518 0.39761 0.07798 57681.338443 0.000599 0.20735 0.03266 0.98068 0 3.68091 0.24244 2.35063 0.15481 0.76323 0.10922 0.48838 0.06987 57681.339381 0.000333 0.21495 0.05061 0.96522 0 2.89577 0.28875 1.84047 0.18340 0.62245 0.13276 0.39706 0.08465 57681.340029 0.000315 0.20230 0.04843 0.97248 0 3.07448 0.30254 1.96992 0.19384 0.62195 0.13573 0.39689 0.08661 57681.341033 0.000689 0.21064 0.03354 0.97059 0 3.11884 0.20675 2.01957 0.13386 0.65694 0.09511 0.42474 0.06148 57681.342092 0.000365 0.15314 0.03738 0.96032 0 3.34018 0.30073 2.12037 0.19085 0.51152 0.11607 0.32689 0.07416 57681.343460 0.001004 0.19806 0.02511 0.98473 0 3.48933 0.18176 2.23409 0.11634 0.69109 0.07988 0.44257 0.05115 57681.803152 0.000356 0.27457 0.04395 0.98374 0 3.65376 0.27191 3.03961 0.22619 1.00323 0.14217 0.83552 0.11840 57681.803904 0.000396 0.19257 0.03009 0.96350 0 4.70200 0.29425 3.89778 0.24390 0.90547 0.12965 0.75071 0.10747 57681.804616 0.000315 0.27501 0.04420 0.98165 0 4.05905 0.30340 3.38248 0.25283 1.11628 0.15884 0.93112 0.13248 57681.805305 0.000373 0.19297 0.03025 0.98450 0 4.86471 0.31044 4.04886 0.25837 0.93875 0.13441 0.78027 0.11170 57681.805993 0.000315 0.26381 0.04248 0.94495 0 4.44813 0.32777 3.63436 0.26780 1.17348 0.16799 0.96208 0.13773 57681.806644 0.000336 0.25092 0.03975 0.98276 0 4.20202 0.30002 3.49603 0.24960 1.05439 0.14912 0.87866 0.12426 57681.807359 0.000379 0.21503 0.03492 0.98473 0 4.20699 0.28366 3.46814 0.23383 0.90462 0.13364 0.74738 0.11036 57681.808068 0.000330 0.24596 0.03918 0.96491 0 4.47046 0.31757 3.72215 0.26439 1.09956 0.15675 0.91419 0.13033 57681.808745 0.000347 0.21855 0.03553 0.98333 0 4.51356 0.30698 3.74385 0.25462 0.98643 0.14566 0.81705 0.12065 57681.809755 0.000663 0.20208 0.02479 0.93450 0 4.49555 0.22393 3.74350 0.18647 0.90844 0.10185 0.75761 0.08492
