/* ** ** 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 56463.281717 0.001059 0.33551 0.02765 0.96721 0 6.16397 0.25393 3.33778 0.13745 2.06805 0.14763 1.12308 0.08011 56463.283760 0.000978 0.34635 0.02871 0.97041 0 6.46041 0.27004 3.49828 0.14622 2.23757 0.16016 1.21192 0.08673 56463.285681 0.000943 0.36136 0.03008 0.97853 0 6.38748 0.27419 3.44964 0.14807 2.30816 0.16465 1.24630 0.08890 56463.286937 0.000312 0.24084 0.03896 0.95370 0 7.23640 0.50975 3.92368 0.27640 1.74282 0.25381 0.94744 0.13799 56463.287565 0.000315 0.31699 0.05182 0.94495 0 5.57301 0.44065 3.03676 0.24011 1.76661 0.25280 0.96247 0.13771 56463.288815 0.000935 0.38884 0.03279 0.96594 0 6.04560 0.26839 3.28193 0.14569 2.35076 0.16856 1.27552 0.09145 56463.291034 0.001285 0.31136 0.02339 0.95495 0 6.57430 0.23856 3.56331 0.12930 2.04697 0.13466 1.10990 0.07301
