/* ** ** 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 55040.786820 0.000466 0.24029 0.03831 0.96273 0 3.17328 0.22260 2.66094 0.18665 0.76251 0.10916 0.63939 0.09152 55040.787685 0.000399 0.29364 0.04813 0.97826 0 2.95192 0.22964 2.50985 0.19525 0.86681 0.12504 0.73715 0.10634 55040.788562 0.000477 0.22163 0.03511 0.98182 0 3.25011 0.22072 2.76113 0.18751 0.72033 0.10311 0.61176 0.08757 55040.789545 0.000506 0.22962 0.03657 0.96000 0 3.00321 0.20432 2.55483 0.17382 0.68958 0.09930 0.58675 0.08450 55040.790497 0.000446 0.27534 0.04425 0.97403 0 2.83861 0.21216 2.41301 0.18035 0.78159 0.11120 0.66424 0.09450 55040.791467 0.000524 0.22500 0.03570 0.97790 0 2.93757 0.20106 2.48510 0.17009 0.66095 0.09463 0.55991 0.08014 55040.792372 0.000382 0.30463 0.04949 0.96970 0 3.02274 0.23701 2.55217 0.20012 0.92080 0.13101 0.77840 0.11075 55040.793194 0.000440 0.24172 0.03773 0.97368 0 3.35476 0.23127 2.85589 0.19688 0.81092 0.11355 0.69034 0.09667 55040.794149 0.000515 0.21751 0.03418 0.98315 0 3.08680 0.20589 2.61521 0.17442 0.67142 0.09553 0.56935 0.08100 55040.795107 0.000443 0.27097 0.04265 0.98039 0 2.99561 0.21847 2.55022 0.18599 0.81173 0.11322 0.69095 0.09637 55040.796039 0.000489 0.22079 0.03495 0.98225 0 3.20412 0.21658 2.70535 0.18287 0.70743 0.10127 0.59702 0.08546 55040.796930 0.000402 0.23779 0.03706 0.97122 0 3.74112 0.25584 3.18390 0.21774 0.88958 0.12457 0.75682 0.10598
