/* ** ** 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 59528.020576 0.000370 0.25031 0.05761 0.94531 0 4.58257 0.47385 1.56950 0.16070 1.14708 0.23586 0.39736 0.08111 59528.021404 0.000457 0.30037 0.04933 0.98101 0 5.31223 0.42023 2.15909 0.17012 1.59563 0.22968 0.63955 0.09151 59528.022422 0.000561 0.23129 0.03637 0.96907 0 5.70621 0.39006 2.31747 0.15824 1.31979 0.18689 0.53280 0.07535 59528.023603 0.000619 0.19297 0.03049 0.97196 0 6.05476 0.38280 2.45252 0.15505 1.16837 0.16919 0.47160 0.06829 59528.024737 0.000515 0.27944 0.04531 0.96067 0 5.19536 0.39294 2.10148 0.15889 1.45178 0.20822 0.58536 0.08388 59528.025764 0.000512 0.24333 0.03952 0.97175 0 5.58578 0.40051 2.34145 0.16777 1.35919 0.19807 0.56730 0.08263 59528.026774 0.000498 0.24997 0.03978 0.97093 0 5.68308 0.41428 2.38220 0.17351 1.42059 0.20097 0.59980 0.08482 59528.027746 0.000475 0.24697 0.03930 0.97561 0 6.19947 0.45093 2.52523 0.18351 1.53111 0.21670 0.62604 0.08854 59528.028690 0.000469 0.24166 0.03920 0.98148 0 6.15684 0.43882 2.54722 0.18145 1.48786 0.21679 0.61368 0.08939 59528.029859 0.000700 0.26709 0.03150 0.96694 0 7.22364 0.39121 2.93590 0.15895 1.92936 0.20212 0.78955 0.08265
