/* ** ** 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 59011.031879 0.000333 0.13658 0.03257 0.94783 0 3.25672 0.26971 2.69791 0.22342 0.44482 0.09947 0.36758 0.08219 59011.032771 0.000558 0.23010 0.03656 0.95337 0 2.76992 0.19089 2.34168 0.16137 0.63736 0.09125 0.53859 0.07710 59011.033977 0.000648 0.22755 0.03612 0.95089 0 2.42024 0.16600 2.04447 0.14023 0.55072 0.07883 0.46526 0.06660 59011.035268 0.000642 0.19894 0.03085 0.97748 0 2.74408 0.17464 2.32018 0.14766 0.54590 0.07720 0.46160 0.06528 59011.036422 0.000512 0.25248 0.04037 0.97175 0 2.74636 0.20025 2.28795 0.16683 0.69339 0.09868 0.57927 0.08242 59011.037533 0.000599 0.21220 0.03317 0.98551 0 2.73412 0.18203 2.31300 0.15399 0.58018 0.08205 0.49101 0.06944 59011.038601 0.000469 0.17048 0.03345 0.96296 0 2.74014 0.20523 2.31451 0.17335 0.46715 0.08472 0.39468 0.07158 59011.039582 0.000512 0.23427 0.03714 0.97175 0 2.92519 0.20468 2.47207 0.17297 0.68528 0.09750 0.57927 0.08242 59011.040878 0.000784 0.18096 0.02657 0.92989 0 2.92691 0.16524 2.47810 0.13991 0.52966 0.07177 0.44840 0.06076
