/* ** ** 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 54964.404062 0.000414 0.30424 0.04222 0.97203 0 3.94069 0.26105 3.22480 0.21360 1.19890 0.14619 0.98328 0.11989 54964.404771 0.000295 0.26802 0.04280 0.99020 0 4.49272 0.33327 3.69959 0.27439 1.20413 0.17030 0.99175 0.14025 54964.405381 0.000315 0.26365 0.04242 0.99083 0 4.17739 0.30740 3.48178 0.25621 1.10137 0.15759 0.91787 0.13134 54964.406000 0.000304 0.28042 0.04453 0.98095 0 4.27734 0.32017 3.54409 0.26526 1.19944 0.16797 0.99194 0.13890 54964.407013 0.000709 0.29222 0.03059 0.96735 0 4.13724 0.20447 3.41010 0.16853 1.20897 0.11158 0.99525 0.09185 54964.408046 0.000324 0.27392 0.04325 0.98214 0 4.14498 0.30245 3.40175 0.24821 1.13538 0.15900 0.92882 0.13006 54964.408758 0.000388 0.20671 0.03249 0.97761 0 4.41865 0.28708 3.65783 0.23764 0.91339 0.13070 0.75672 0.10828 54964.409545 0.000399 0.22118 0.03538 0.98551 0 3.93636 0.26771 3.25598 0.22144 0.87064 0.12607 0.72128 0.10444 54964.410346 0.000402 0.28690 0.03987 0.98561 0 4.15058 0.27357 3.43827 0.22661 1.19080 0.14567 0.98679 0.12070 54964.411113 0.000365 0.21070 0.03338 0.99206 0 4.49352 0.29715 3.74551 0.24769 0.94680 0.13628 0.78890 0.11355 54964.411782 0.000304 0.27304 0.04364 0.98095 0 4.31402 0.31946 3.59687 0.26635 1.17788 0.16685 0.98188 0.13908 54964.412551 0.000466 0.25551 0.03255 0.97516 0 4.68079 0.26942 3.88467 0.22358 1.19600 0.13593 0.99199 0.11274 54964.413370 0.000353 0.24431 0.03916 0.96721 0 4.10330 0.28938 3.42062 0.24124 1.00247 0.14430 0.83569 0.12029 54964.414047 0.000324 0.27308 0.04373 0.97321 0 4.01811 0.29555 3.34760 0.24623 1.09726 0.15609 0.91421 0.13005 54964.414791 0.000420 0.26134 0.03691 0.97241 0 4.18617 0.26946 3.49053 0.22468 1.09400 0.13755 0.91250 0.11473
