/* ** ** 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 59055.979482 0.000466 0.26949 0.04331 0.97516 0 2.74402 0.20528 2.35446 0.17614 0.73950 0.10519 0.63472 0.09029 59055.980382 0.000434 0.32082 0.05231 0.97333 0 2.52773 0.20416 2.16172 0.17459 0.81096 0.11486 0.69273 0.09812 59055.981322 0.000506 0.24937 0.03989 0.96000 0 2.76966 0.19793 2.36723 0.16916 0.69067 0.09884 0.59009 0.08443 59055.982428 0.000599 0.20067 0.03164 0.95169 0 2.93072 0.18864 2.49998 0.16090 0.58811 0.08465 0.50060 0.07205 59055.983539 0.000512 0.26678 0.04285 0.95480 0 2.57649 0.19215 2.21029 0.16484 0.68735 0.09777 0.58965 0.08388 59055.984520 0.000469 0.25145 0.04068 0.96296 0 2.94035 0.21717 2.51268 0.18554 0.73934 0.10643 0.63217 0.09099 59055.985605 0.000616 0.23417 0.03742 0.94836 0 2.42908 0.16855 2.08508 0.14468 0.56881 0.08187 0.48821 0.07027 59055.986739 0.000518 0.23418 0.03703 0.95531 0 2.90083 0.20040 2.48847 0.17192 0.67933 0.09663 0.58275 0.08290 59055.987760 0.000503 0.28193 0.04537 0.95977 0 2.49256 0.19134 2.12917 0.16343 0.70272 0.09938 0.59980 0.08482 59055.988799 0.000535 0.24547 0.03946 0.94054 0 2.69081 0.19271 2.30898 0.16537 0.66051 0.09506 0.56678 0.08157 59055.990133 0.000799 0.26709 0.03318 0.97464 0 2.72273 0.15783 2.33025 0.13508 0.72721 0.07990 0.62174 0.06831
