/* ** ** 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 56383.024315 0.001021 0.26843 0.02163 0.98017 0 4.73928 0.17453 4.26957 0.15722 1.27217 0.09116 1.14583 0.08211 56383.026286 0.000949 0.28000 0.02278 0.99085 0 4.83584 0.18387 4.34771 0.16530 1.35401 0.09736 1.21664 0.08747 56383.028117 0.000883 0.30905 0.02538 0.98033 0 4.75584 0.18846 4.27889 0.16955 1.46981 0.10570 1.32243 0.09508 56383.029946 0.000946 0.29776 0.02414 0.97248 0 4.67034 0.18137 4.21137 0.16353 1.39062 0.09899 1.25334 0.08922 56383.031870 0.000972 0.26933 0.02165 0.97917 0 4.96582 0.18339 4.48267 0.16554 1.33745 0.09552 1.20824 0.08629 56383.034107 0.001264 0.25933 0.01849 0.99542 0 5.00836 0.16252 4.52749 0.14691 1.29883 0.08244 1.17563 0.07461
