/* ** ** 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 54963.881199 0.000330 0.30886 0.05011 0.97368 0 3.64990 0.28466 2.92484 0.22805 1.12733 0.16039 0.89771 0.12771 54963.881885 0.000356 0.34782 0.05728 0.95935 0 3.05233 0.25746 2.44707 0.20636 1.06167 0.15015 0.84887 0.12005 54963.882640 0.000399 0.23889 0.03806 0.97826 0 3.90510 0.27187 3.10024 0.21583 0.93288 0.13370 0.74136 0.10626 54963.883358 0.000318 0.29037 0.04668 0.99091 0 3.96326 0.30287 3.16525 0.24188 1.15080 0.16275 0.91896 0.12996 54963.884050 0.000373 0.24016 0.03813 0.99225 0 4.05370 0.28570 3.24218 0.22850 0.97353 0.13849 0.77848 0.11074 54963.884785 0.000362 0.28566 0.04583 0.92800 0 3.77114 0.27973 3.00756 0.22309 1.07727 0.15325 0.85901 0.12220 54963.885485 0.000339 0.26841 0.04339 0.99145 0 3.99130 0.30022 3.18508 0.23957 1.07131 0.15330 0.85452 0.12228 54963.886312 0.000489 0.22581 0.03547 0.98225 0 3.35223 0.22907 2.67189 0.18258 0.75697 0.10705 0.60341 0.08534 54963.887308 0.000506 0.19253 0.03013 0.98857 0 3.72951 0.23640 2.97748 0.18873 0.71805 0.10276 0.57297 0.08199 54963.888170 0.000356 0.28883 0.04668 0.97561 0 3.61555 0.27737 2.87442 0.22052 1.04427 0.14855 0.83038 0.11813 54963.888992 0.000466 0.24091 0.03839 0.96273 0 3.33645 0.23400 2.65532 0.18623 0.80379 0.11503 0.63951 0.09152 54963.889782 0.000324 0.28918 0.04649 0.98214 0 3.94366 0.30142 3.14753 0.24057 1.14042 0.16128 0.91061 0.12878 54963.890528 0.000422 0.23953 0.03839 0.97945 0 3.62318 0.25536 2.87687 0.20275 0.86786 0.12494 0.68953 0.09926 54963.891283 0.000333 0.30245 0.04965 0.96522 0 3.69620 0.29166 2.93590 0.23167 1.11791 0.16093 0.88831 0.12788 54963.892021 0.000405 0.28096 0.04294 0.96429 0 3.66889 0.26240 2.92989 0.20955 1.03083 0.13921 0.82329 0.11118
