/* ** ** 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 59695.096658 0.000674 0.25113 0.02036 0.99142 0 7.70002 0.27881 6.75910 0.24472 1.93368 0.14031 1.69896 0.12329 59695.098111 0.000778 0.21174 0.01670 0.98141 0 8.08410 0.26679 7.10280 0.23440 1.71169 0.12261 1.50213 0.10760 59695.099511 0.000622 0.28492 0.02298 0.96744 0 7.67135 0.29086 6.73199 0.25519 2.18569 0.15555 1.91642 0.13639 59695.100874 0.000741 0.22329 0.01769 0.98438 0 8.01133 0.27092 7.04092 0.23809 1.78883 0.12813 1.57366 0.11272 59695.102295 0.000680 0.24728 0.01988 0.98298 0 7.82144 0.27853 6.90644 0.24595 1.93409 0.13944 1.70784 0.12313 59695.104274 0.001299 0.22286 0.01338 0.97264 0 8.09008 0.20578 7.11408 0.18095 1.80295 0.09802 1.58664 0.08626 59695.165811 0.001085 0.23399 0.01878 0.96267 0 6.33476 0.22026 4.66306 0.16204 1.48227 0.10726 1.08989 0.07884 59695.167805 0.000909 0.29924 0.02480 0.98089 0 5.85162 0.23345 4.26129 0.17001 1.75104 0.12723 1.27725 0.09276 59695.169752 0.001039 0.23233 0.01814 0.97772 0 6.75416 0.22995 5.00852 0.17046 1.56919 0.11025 1.16139 0.08157
