/* ** ** 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 56485.040540 0.000347 0.39022 0.03341 0.99167 0 9.29353 0.42431 8.50646 0.38832 3.62650 0.26268 3.32220 0.24065 56485.041254 0.000367 0.35000 0.02947 0.99213 0 9.75934 0.41572 8.92777 0.38027 3.41575 0.24807 3.12173 0.22673 56485.041958 0.000336 0.39817 0.03381 1.00000 0 9.34326 0.42577 8.59863 0.39180 3.72022 0.26659 3.42244 0.24526 56485.042609 0.000315 0.38443 0.03251 1.00000 0 10.34640 0.46480 9.47446 0.42564 3.97742 0.28501 3.64223 0.26101 56485.043263 0.000339 0.36691 0.03166 1.00000 0 9.92291 0.44160 9.06726 0.40356 3.64085 0.26917 3.33201 0.24626 56485.043974 0.000373 0.34215 0.02876 0.97674 0 9.99585 0.41755 9.13259 0.38146 3.42010 0.24945 3.12309 0.22775 56485.044698 0.000350 0.35693 0.02999 0.99174 0 10.09078 0.43288 9.27541 0.39782 3.60170 0.26023 3.31121 0.23923 56485.045450 0.000402 0.30922 0.02597 0.98561 0 10.01375 0.40425 9.20410 0.37154 3.09642 0.22800 2.84434 0.20938 56485.046208 0.000356 0.37468 0.03193 0.98374 0 9.45055 0.41647 8.68140 0.38253 3.54093 0.25825 3.25215 0.23716 56485.046903 0.000339 0.37064 0.03170 1.00000 0 9.77958 0.43412 9.02829 0.40077 3.62466 0.26503 3.34621 0.24467 56485.047574 0.000333 0.39383 0.03301 1.00000 0 9.67743 0.43548 8.82922 0.39732 3.81124 0.26951 3.48406 0.24636 56485.048294 0.000388 0.32100 0.02669 0.99254 0 10.07304 0.41142 9.26007 0.37823 3.23340 0.23421 2.97250 0.21532 56485.049070 0.000388 0.37249 0.03192 0.98507 0 8.62946 0.38141 7.96596 0.35208 3.21439 0.23598 2.96725 0.21784 56485.049848 0.000391 0.32922 0.02745 0.99259 0 9.75028 0.40752 8.96070 0.37447 3.20996 0.23161 2.94904 0.21275 56485.050612 0.000373 0.33502 0.02767 1.00000 0 10.05141 0.41886 9.27880 0.38667 3.36747 0.24009 3.10860 0.22163 56485.051515 0.000530 0.33283 0.02307 0.99454 0 10.14507 0.35587 9.36507 0.32851 3.37657 0.20189 3.11696 0.18637
