/* ** ** Swift/XRT hardness ratio for 1ES 1218+304. ** 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 58897.353600 0.000988 0.16224 0.03906 0.97059 1 2.93679 0.26216 0.74604 0.06660 0.47646 0.10654 0.12121 0.02710 58897.355256 0.000668 0.21325 0.05250 0.93478 1 3.41894 0.35230 0.86982 0.08963 0.72909 0.16303 0.18605 0.04160 58897.356622 0.000697 0.22651 0.05645 1.00000 1 2.87880 0.31681 0.73379 0.08075 0.65207 0.14581 0.16667 0.03727 58897.358074 0.000755 0.20868 0.05161 0.94231 1 3.05424 0.31105 0.77813 0.07924 0.63737 0.14365 0.16207 0.03653 58897.359294 0.000465 0.28059 0.07132 1.00000 1 3.51435 0.42484 0.89376 0.10804 0.98609 0.22050 0.25000 0.05590 58897.360442 0.000683 0.24182 0.06101 0.95745 1 2.85269 0.31304 0.72661 0.07973 0.68984 0.15671 0.17517 0.03980 58897.362156 0.001002 0.31956 0.05969 0.96945 1 2.78386 0.25441 0.70832 0.06473 0.88960 0.14491 0.22636 0.03687
