/* ** ** 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 59722.140734 0.000694 0.26303 0.02106 0.97917 0 8.09465 0.29601 6.45259 0.23591 2.12914 0.15168 1.70033 0.12110 59722.142187 0.000758 0.23261 0.01841 0.97710 0 8.34919 0.28789 6.71442 0.23149 1.94207 0.13831 1.56085 0.11116 59722.143547 0.000602 0.30064 0.02450 0.95673 0 8.24220 0.32388 6.65246 0.26141 2.47794 0.17694 1.99786 0.14265 59722.144756 0.000608 0.27176 0.02222 0.97619 0 8.75134 0.32937 7.04546 0.26517 2.37831 0.17262 1.91425 0.13893 59722.145951 0.000587 0.30399 0.02538 0.98030 0 7.99082 0.32260 6.45050 0.26042 2.42916 0.17749 1.96161 0.14331 59722.147572 0.001033 0.24861 0.01659 0.97898 0 8.22624 0.24435 6.64295 0.19730 2.04511 0.12223 1.65279 0.09877
